Ultra long duration balloons (ULDB) are being developed which can operate at float for +100 days. The limiting factor is the diurnal cycle of the sun, rising and setting. Heat during the day causes the balloon to expand and gain altitude, thereby losing helium . Heat loss at night causes the balloon to sink and contract.

There is currently an ongoing investigation by the Interstate Aviation Committee and others. They have found that the crew had chosen to fly at minimum altitude over the area. In the last few seconds preceding the crash, the crew attempted to gain altitude. The thick smoke may have led to the choice of flight profile.

Then, "he began to climb, until the plane was nearly vertical and it began to stall and shake." The aircraft ground collision alarm sounded, alarming all of the passengers. The pilot applied maximum power in an attempt to gain altitude. Witness accounts and evidence at the scene indicated the plane struck the mountain either two or three times.

The floating balloons released by the plants are full of explosive hydrogen, and when a fire hits, they explode like bombs, releasing seeds flying through the air. Skywhales and Kites will gain altitude until the fire ends. The ghost traps sway from branch to branch like monkeys using their tentacles. The Stalkers' escape strategy is unknown.

Some conventional aircraft can perform similar maneuvers, but with differences, such as being performed at low speed, changing alpha too slowly, or using low thrust so as not to gain altitude, i.e. performing a forced stall climb with no thrust, usually ending with the aircraft performing a climb or stalling instead of completing the cobra movement.
|
|
To make an aircraft climb, i.e. gain altitude, the pilot will raise the nose higher than it is in the cruise attitude. For many light aircraft, this will correspond to a sight picture where the aircraft nose appears to be on or just slightly above the horizon. The amount of movement will typically not exceed 10-15 degrees.

As coal extraction developed, pits were opened further north and east than the M&KR; reached, and the Ballochney Railway was constructed to serve some of them, running from Kipps, near Coatbridge, to pits around Arbuckle and Clarkston, and a quarry. It opened in 1828. The area it reached was on high ground, and two rope-worked inclines were necessary to gain altitude.

As with most buzzards, these birds utilize rising air currents to gain altitude and cover great distances by soaring during migration. Taiwan lies on a major migration route for the Grey faced buzzard, and large numbers may be seen moving southward in October along the Hengchun Peninsula, and northward in late March and early April along the terraced mountains of Taichung and Changhua.

The bomber caught fire and began to lose altitude as its pilot attempted to crash-land the plane. Two of the Tonys escorting the bomber stayed with it as it went down. Shomo pulled up in a tight vertical spiral to gain altitude while the Tojo turned to engage him. The Japanese fighter fired until it stalled and slipped into the clouds.

Cumulus humilis may be accompanied by other cloud types. Air below the cloud base can be quite turbulent due to the thermals that formed the clouds, giving occupants of light aircraft an uncomfortable ride. To avoid turbulence where such clouds are present, pilots may climb above the cloud tops. However, glider pilots actively seek out the rising air to gain altitude.

Using mountain ridges to gain altitude A ridge soaring pilot uses upward air movements caused when the wind blows on to the sides of hills. It can also be augmented by thermals when the slopes also face the sun. In places where a steady wind blows, a ridge may allow virtually unlimited time aloft, although records for duration are no longer recognized because of the danger of exhaustion.

The boundaries where two air masses meet are known as convergence zones. These can occur in sea breezes or in desert regions. In a sea-breeze front, cold air from the sea meets the warmer air from the land and creates a boundary between two masses of air like a shallow cold front. Glider pilots can gain altitude by flying along the intersection as if it were a ridge of land.

On July 17, Tinker shot down another Bf 109A. This first version of the Bf 109 was not a "good climber" and Tinker caught it from behind while the German pilot tried to gain altitude after a dive on him – a lethal mistake according to Tinker. The scene is described in detail in his book Some Still Live. His final victory was over a Fiat CR.32 on July 18, 1937.

He radioed his flight leader saying that he could not retract his nose gear, and thus couldn't gain altitude. He was at an height high enough to bail out, but too low that if he did, he would've hit Lincoln Elementary School, which was in session with 800 students. He kept the plane nose up long enough to pass the school, and eventually hit nine residential houses on Lenwood Avenue.

The load would be placed in the doorway, and three or four men would push it out when the pilot gave the signal. The pilot would fly level or with the nose slightly down, so that cargo would not hit the tail of the aircraft. The pilot would retract the landing gear if it was down, and climb to gain altitude. Multiple passes over the drop zone might be required.

Fending off Japanese soldiers, the crew pick up three survivors, the fourth being killed. They are then attacked by three fighter aircraft. With the airship punctured and losing gas, the crew jettison as much as they can to gain altitude; when that is not enough to reach clouds to hide in, both Trumpet and Jimmy Shannon (James Gleason) parachute out. Allied P-38 Lightnings fly to their rescue.

To gain altitude and speed more quickly, the airship commander (Carl von Haartman) decides to sacrifice Karl by cutting the cable that secures his pod. When that is not enough, he orders everything possible be jettisoned. He then accepts the advice of another officer; the officer and other crewmen obediently leap to their deaths "for Kaiser and fatherland". German machine gunners shoot down three aircraft; Roy and Monte survive a crash landing.

Illustrious was the main target and was enveloped in waterspouts and mist of exploding bombs. Some bombers diving from an altitude of 12,000 feet delayed bomb release until they pulled-out lower than the height of Illustrious funnel. The five air patrol Fulmars had not returned from chasing the SM.79s which attacked Valiant and the four recently launched Fulmars were unable to gain altitude rapidly enough to break up the attack.

Animal aerial locomotion can be divided into two categories—powered and unpowered. In unpowered modes of locomotion, the animal uses aerodynamics forces exerted on the body due to wind or falling through the air. In powered flight, the animal uses muscular power to generate aerodynamic forces to climb or to maintain steady, level flight. Those who can find air that is rising faster than they are falling can gain altitude by soaring.

The weather was heavy fog and rain. A large cold front was moving onshore; it had already caused the loss of a Coast Guard helicopter. Going northwest from San Francisco Bay, Flight 282 was to head out over the ocean to circle and gain altitude, then travel east toward its destination of JFK International Airport in New York City. Shortly after takeoff, however, the plane veered to the left of its planned course.

Chiapas occupies the extreme southeast of Mexico; it possesses of Pacific coastline. Chiapas features two principal highland regions; to the south is the Sierra Madre de Chiapas and in central Chiapas are the Montañas Centrales (Central Highlands). They are separated by the Depresión Central, containing the drainage basin of the Grijalva River, featuring a hot climate with moderate rainfall. The Sierra Madre highlands gain altitude from west to east, with the highest mountains near the Guatemalan border.

The accident killed 37 passengers and crew; three passengers and a crewmember survived the crash, and were rescued shortly after the crash. Bermuda's Director of Civil Aviation, E. M. Ware, said at the time that the take-off apparently had been normal. It is believed no message came from the plane before it plunged into the sea, probably while still pushing the engines hard to gain altitude. Four survivors were taken to the Kindley base hospital.

Osprey Publishing, 2008, p. 42 From the pilot's standpoint, performing an extraction using a McGuire Rig required intense concentration. Once the soldiers were in the rig, the pilot would attempt to gain altitude by rising straight up, but with the nearest ground reference over 100 feet away, it was difficult to discern when the chopper was moving. There was the distinct possibility, therefore, that the soldier(s) would be dragged through tree limbs during the extraction.

On the return from Longuyon, the squadron had its first "Close In" combat with enemy scout planes. The formation had dwindled down to five planes, which were seen by members of the German pursuit squadron stationed near Longuyon. Upon approaching the objective, the pilots and observers flew the enemy planes taking off from their field, and watched them gain altitude in remarkable short time. The enemy planes, numbering four, attacked from the sun, opening fire at 400 yards distance.

Bar-headed geese Anser indicus have been recorded by GPS flying at up to while crossing the Himalayas, at the same time engaging in the highest rates of climb to altitude for any bird. Anecdotal reports of them flying much higher have yet to be corroborated with any direct evidence. Seabirds fly low over water but gain altitude when crossing land, and the reverse pattern is seen in landbirds. However most bird migration is in the range of .

Two of the aircraft departed after their fuel tanks were depleted, leaving him with one wingman to continue the patrol. Soon after, the two pilots spotted a formation of four MiGs taking off from Antung airfield on the Chinese side of the Yalu River. Despite being low on fuel, Bolt ordered an attack. He made a head-on dive toward the formation, which was attempting to gain altitude, and downed the leading airplane with four machine gun bursts.

Sailplane (Rolladen-Schneider LS4) Gunma, Japan. A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring).FAA Glider handbookDefinition of gliders used for sporting purposes in FAI Sporting Code This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude.

He ran for the door towards a Hurricane. His adjutant, George Rumsey, tried to stop him, but Pattle was determined to fly. On the way to his fighter, he narrowly avoided being killed in a strafing attack by a low-flying Bf 110\. He took to the skies minutes later. Pattle climbed to gain altitude and headed for Piraeus Harbour at 20,000 feet. At this time, other Hurricanes were already in action with Bf 110s from Zerstörergeschwader 26 (ZG 26).

On 27 July 1944, two Douglas C-47 Skytrains (one was serial number 42-93038) of the United States Army Air Forces were on a flight from Filton to a stop at Prestwick before flying on to the United States. The flight was transporting wounded soldiers. The flight encountered bad weather, and the pilot of 42-93038 tried to gain altitude to clear the cliffs. The C-47 crashed into the cliff side at Port Logan, where all 22 passengers and crew died.

The main operation got under way at Twenty Nine Palms Army Airfield, in the California desert, where thermal conditions were great for soaring flights. Sailplane thinking still prevailed. By being able to soar – gain altitude on rising air currents – and therefore stay up longer on a given flight, the student would conceivably receive more instruction per flight. It was not long, however, before the military woke up to the fact that troop gliders were not simply bigger sailplanes that made long straight glides into enemy territory.

In rockets, this means that the vehicle the engine is attached to can more efficiently gain altitude and velocity. This effectiveness is less important in jet aircraft that use ambient air for combustion, and carry payloads that are much heavier than the propellant. Specific impulse can include the contribution to impulse provided by external air that has been used for combustion and is exhausted with the spent propellant. Jet engines use outside air, and therefore have a much higher specific impulse than rocket engines.

Although Hell's Wench was in flames and had been seriously damaged by German anti-aircraft guns, Baker maintained formation and bombed his target. Subsequently, Baker broke formation to avoid a mid-air collision with bombers from the lead group, now arriving in the target area from the opposite direction. He attempted to gain altitude so that his crew could escape by parachute, but despite his efforts, Hell's Wench crashed and exploded, killing Baker and the other nine airmen aboard. On 11 March 1944, Colonel Baker was posthumously awarded the Medal of Honor.

The final accident report, which was published by France's Bureau d'Enquêtes et d'Analyses pour la Sécurité de l'Aviation Civile (BEA), concluded that the crash occurred due to the airplane being overloaded, as the plane's actual weight exceeded its maximum weight capacity, thus decreasing its performance, especially when taking off. Flight 141 did take off, but could not gain altitude, hit a localizer building, and plunged into the ocean. The report also blamed the airport's lack of facilities. The crash was the 102nd aviation accident involving the Boeing 727.

Less radical is the assessment that due to the lack of a keeled sternum and a high acrocoracoid, the musculus pectoralis minor could not serve as a M. supracoracoideus lifting the humerus via a tendon running through a . This, coupled with a limited upstroke caused by a lateral position of the shoulder joint, would have made it difficult to gain altitude. Some authors, therefore, proposed that Confuciusornis used its large thumb claws to climb tree trunks. Martin assumed that it could raise its torso almost vertically like a squirrel.

Controlled flight into terrain (CFIT) is a class of accidents in which an aircraft is flown under control into terrain or man-made structures. CFIT accidents typically result from pilot error or of navigational system error. Failure to protect ILS critical areas can also cause CFIT accidents. In December 1995, American Airlines Flight 965 tracked off course while approaching Cali, Colombia and hit a mountainside despite a terrain awareness and warning system (TAWS) terrain warning in the cockpit and desperate pilot attempt to gain altitude after the warning.

The aircraft was conveying the body of former governor of Ondo State Olusegun Agagu from Lagos to Akure for burial. It lifted off from runway 18L of Murtala Mohammed Airport at about 09:32 local time (08:32 UTC). The crew received warnings from the aircraft's aural warning system during the takeoff-roll and also failed to make "V1" and "rotate" calls; the aircraft then struggled to gain altitude immediately after takeoff.Crash: Associated E120 at Lagos on Oct 3rd 2013, lost height after takeoff UPDATE The Aviation Herald.

The Darjeeling Himalayan Railway, also known as the DHR or the Toy Train, is a gauge railway that runs between New Jalpaiguri and Darjeeling in the Indian state of West Bengal. Built between 1879 and 1881, it is about long. It climbs from about above sea level at New Jalpaiguri to about at Darjeeling, using six zig zags and five loops to gain altitude. Six diesel locomotives handle most of the scheduled service, with daily tourist trains from Darjeeling to Ghum – India's highest railway station – and the steam-hauled Red Panda service from Darjeeling to Kurseong.

The cloud ceiling was 300 feet, with visibility of 3/4 of a mile, and there was little contrast between the sky and the calm waters of the bay. As a result, once the plane descended below the clouds, the mistake was not recognized in time to correct it before hitting the water. Captain Asoh stated that he realized the plane was too low once he spotted the water after the plane broke through the fog at an altitude of with an air speed of . He grabbed the control stick to gain altitude, but the plane had already struck the water.

Once the skills of using thermals to gain altitude have been mastered, pilots can glide from one thermal to the next to go cross country. Having gained altitude in a thermal, a pilot glides down to the next available thermal. Potential thermals can be identified by land features that typically generate thermals or by cumulus clouds, which mark the top of a rising column of warm, humid air as it reaches the dew point and condenses to form a cloud. Cross-country pilots also need an intimate familiarity with air law, flying regulations, aviation maps indicating restricted airspace, etc.

On rare occasions, when Wildcats were unable to gain altitude in time, they would suffer many losses. On 2 October 1942, a Japanese air raid from Rabaul was not detected in time and the Cactus Air Force lost six Wildcats to only one Zero destroyed.Lundstrom 1994, pp. 266–270, Stille 2019, Kindle location 1233–1237. During the most intense initial phase of the Guadalcanal Campaign, between 1 August and 15 November, combat records indicate that US lost 115 Wildcats and Japanese lost 106 Zeros to all causes; the Japanese lost many more pilots compared to the US.Stille 2019, Kindle location 1895–1925.

During testing one of the two Quad vehicles (named Texel) crashed on a tethered flight after a guidance problem caused the vehicle to rapidly gain altitude until 3 separate flight termination procedures were activated at approximately 20–30 feet. The vehicle fell, and the impact broke open one of the alcohol tanks and a large fireball engulfed the vehicle.Texel crash video The vehicle was irreparably damaged, and only its sister Pixel could compete in the upcoming event. The plan was to have the first module (of the next generation modular design) compete at level 1, and have Pixel compete at level 2 challenge.

The takeoff was normal until the main wheels left the ground, at which point the aircraft commenced a violent rolling motion and the right wing dropped. The aircraft's tail made contact with the runway briefly, and later, the right wingtip struck the runway. The aircraft developed compressor surges (due to breakdown of the airflow through the engine), and was unable to gain altitude or maintain stabilized flight. Approximately beyond the end of runway 18L, the plane's right wing hit the ILS localizer antenna, which set the wing on fire and caused it to start disintegrating while the plane was still in flight.

Similarly, to further protect the wearer, the engines are modified by adding a carbon fiber heat shield extending the jet nozzle around the exhaust tail. Rossy claims to be "the first person to gain altitude and maintain a stable horizontal flight thanks to aerodynamic carbon foldable wings", which are folded by hinges at their midpoint. After being lifted to altitude by a plane, he ignites the engines just before he exits the plane with the wings folded. The wings unfold while in free-fall, and he then can fly horizontally for several minutes, landing with the help of a parachute.

Repeatedly failing for years to stop the aircraft embarrassed the USSR, which made diplomatic protests against the flights but did not publicize the penetration of Soviet territory. U-2 missions from Wiesbaden would depart westward in order to gain altitude over friendly territory before turning eastward at operational altitudes. The NATO Air Defence mission in that area included No. 1 Air Division RCAF (Europe), which operated the Canadair Sabre Mark 6 from bases in northeastern France. This aircraft had a service ceiling of 54,000 feet and numerous encounters between the U-2 and RCAF 'ZULU' alert flights have been recorded for posterity.

In 1872 the Intercolonial Railway built its mainline between Halifax and Rivière-du-Loup through the valley, rising along its western walls to gain altitude to reach the summit at Folly Lake. Today, these tracks are part of Canadian National Railway's Springhill Subdivision and continue to form part of the mainline from Halifax to central Canada, hosting both freight and passenger trains. Roads followed the railway during the 20th century and Trunk 4 was built through the valley and over Folly Mountain to the south. During the early 1960s this road was redesignated Highway 104, forming part of the Trans-Canada Highway.

Counter-air patrol, known as Flower missions in RAF parlance, is a type of flying mission for fighter aircraft against other fighters, common in World War II and sometimes combined with fighter sweeps (Rhubarb missions) against targets of opportunity. Counter-air patrol is an attempt to achieve air superiority by maintaining patrols above and around enemy airfields. Aircraft are vulnerable on take off, fully loaded and working to gain altitude and speed. The aim of the counter-air patrol was to pick off enemy fighters as they took off and during their climb to an operational height.

Park had experimented with large wings (covering the earlier Dunkirk evacuation) and insisted that they were unwieldy, difficult to manoeuvre into position and rarely in the right place when needed. The 11 Group squadrons were closer to the Luftwaffe than 12 Group and Park pointed out that there was insufficient time over Kent and Sussex for a large formation to gain altitude against the incoming raids. Bader countered by pointing out that his wing could be used as a reserve for 11 Group. Positioned well away from the Luftwaffe bases in France he could be in place at altitude when the wing was needed, providing adequate early warning was given.

Passenger train with a three-axle 3rd class passenger car on the Taubenloch bridge between Biel and Frinvilier-Taubenloch in 1936 After the exit in Biel, trains quickly gain altitude, giving travellers a view of Biel and the Three Lake country (Drei-Seen-Land/Pays des Trois-Lacs). After crossing the Taubenloch gorge, trains arrive at Reuchenette-Péry, where a large concrete factory provides goods traffic. The line runs along the Suze river and the Transjurane motorway to Sonceboz-Sombeval, where the line branches off to Tavannes and Moutier. The line passes through Courtelary to Saint-Imier, the main town of the vallon of Saint-Imier.

On January 13, 1982, during an extraordinary period of freezing weather, Air Florida Flight 90 took off from nearby Washington National Airport, failed to gain altitude, and crashed into the 14th Street Bridge, where it hit six cars and a truck on the bridge, killing four motorists. After the crash on the bridge, the plane then continued forward and plunged into the freezing Potomac River. Soon only the tail section which had broken off remained afloat. Only six of the airliner's 79 occupants (74 passengers and 5 crew members) survived the initial crash and were able to escape the sinking plane in the middle of the ice-choked river.

Video: hauling a cicada up a tree After digging a nest chamber in the burrow, female cicada killers capture cicadas, paralyzing them with a sting. After paralyzing a cicada, the female wasp holds it upside down beneath her and takes off toward her burrow; this return flight to the burrow is difficult for the wasp because the cicada is often more than twice her weight. A wasp will often lug its prey up into the nearest tree, to gain altitude for the flight to the burrow. After putting one or more cicadas in her nest cell, the female deposits an egg on a cicada and closes the cell with dirt.

He ends the first page by explaining that if a bird in a descent wants to turn left or right, then it will lower the wing on the side of the direction it wants to turn. Birds can gain altitude, as stated by Leonardo, by "[raising] the shoulders and [beating] the tips of the wings towards itself, thus condensing the air that stands between the tips of [its] wings and itself". He also describes the flight of a kite as seeking a wind current. When the winds are high, one will see the bird very high in the sky, but when the winds are low, the bird stays closer to the ground.

Rocket sled launch helps a vehicle gain altitude, and proposals commonly involve the track curving up a mountain. Advantages to any launch system that starts from high altitudes include reduce gravity drag (the cost of lifting fuel in a gravity well). The thinner air will reduce air resistance and allow more efficient engine geometries. Rocket nozzles have different shapes (expansion ratios) to maximize thrust at different air pressures. (Though NASA's aerospike engine for the Lockheed Martin X-33 was designed to change geometry to remain efficient at a variety of different pressures, the aerospike engine had added weight and complexity; X-33 funding was canceled in 2001; and other benefits from launch assist would remain even if aerospike engines reached flight testing).

On 1 September 1953, during the first flight of the second Trident I prototype, flown by Guignard, the aircraft crashed after struggling to gain altitude after takeoff and colliding with an electricity pylon, resulting in its loss and Guignard sustaining severe injuries.Pelt 2012, p. 161. On 16 January 1954, test flights using the remaining Trident I prototype were resumed, flown by test pilot Charles Goujon. Partially in response to the loss of the second Trident I due to a lack of engine power, it was decided to adopt new turbojet engines in the form of the more powerful Dassault MD.30 Viper, a license-produced version of the British Armstrong Siddeley Viper engine, which were capable of producing 7.34 kN (1,654 lbf) thrust each, nearly double the thrust of the original engines.

Describing the railway, BuchananDavid Octavius Hill and George Buchanan, Views of the Opening of the Glasgow and Garnkirk Railway. Also an Account of That and Other Railways in Lanarkshire, Edinburgh, 1832 says that "It was commenced in the summer of 1826 and opened to the public on 8 August 1828", but Martin states authoritatively that this represents the final completion of the construction of the whole line. "Revenue-earning traffic on the railway actually commenced very much earlier, on 12 November 1827" although this may only have been over a short distance from Kipps Colliery to the junction with the M&KR.; The line was about in extent,Whishaw: 1842 and it included two self-acting inclined planes to gain altitude in reaching the high ground where the mines were located.

A facility, named Condor Field, was utilized with C-47 Skytrains flown by Women Airforce Service Pilots (WASP)s being used as tow tugs for the gliders, with Laister-Kauffman TG-4A sailplanes used for glider training. However, it was learned that the military gliders under development were fundamentally different in their flight characteristics than sailplanes in their handling, and especially the fact that once released, a military glider did not soar as a sailplane does. The combat gliders under development could not soar and gain altitude once the pilot released the tow line as a sailplane could. They could only descend, and once a pilot committed to a landing and discovered, as he got closer, that the landing zone was under fire, mined, or otherwise obstructed, he had little room to maneuver to make a safe landing.

The aircraft was to have begun its mission propelled along a long rail track by a large rocket-powered sled to about . Once airborne, it was to fire its own rocket engine and continue to climb to an altitude of , at which point it would be travelling at about . It would then gradually descend into the stratosphere, where the increasing air density would generate lift against the flat underside of the aircraft, eventually causing it to "bounce" and gain altitude again, where this pattern would be repeated. Because of aerodynamic drag, each bounce would be shallower than the preceding one, but it was still calculated that the Silbervogel would be able to cross the Atlantic, deliver a bomb to the continental United States, and then continue its flight to a landing site somewhere in the Empire of Japan–held Pacific, a total journey of .

A Boeing 737 airliner is an example of a fixed-wing aircraft delta-shaped kite are not rigid A fixed-wing aircraft is a flying machine, such as an airplane (or aeroplane; see spelling differences), which is capable of flight using wings that generate lift caused by the aircraft's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which the wings form a rotor mounted on a spinning shaft or "mast"), and ornithopters (in which the wings flap in a manner similar to that of a bird). The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft and airplanes that use wing morphing are all examples of fixed-wing aircraft. Gliding fixed-wing aircraft, including free-flying gliders of various kinds and tethered kites, can use moving air to gain altitude.

First, the wake of a steamboat that was navigating on the lake close to the area where the Transaereo was accelerating was thought to have interfered with the takeoff. Second, test pilot Semprini was blamed for having kept pulling the yoke trying to gain altitude while he should have performed corrective maneuvers, for example lowering the nose to let the huge aircraft gain speed. Another theory suggests the aforementioned boat was a ferry loaded with passengers and Semprini (who was only performing some taxiing trials, for he didn't mean to take off before Caproni's arrival on the spot) was suddenly compelled to take off, in spite of the insufficient speed, to avoid a collision. According to more recent theories, the cause of the accident was probably the sandbags that had been placed in the aircraft to simulate the weight of passengers: not having been fastened to the seats, they may have slid to the back of the fuselage when, upon takeoff, the Transaereo suddenly pitched up.

The tyre exploded, and a piece of rubber hit the fuel tank, which caused a fuel leak and led to a fire. The crew shut down engine number 2 in response to a fire warning, and with engine number 1 surging and producing little power, the aircraft was unable to gain altitude or speed. The aircraft entered a rapid pitch-up then a sudden descent, rolling left and crashing tail-low into the Hôtelissimo Les Relais Bleus Hotel in Gonesse. The claim that a metallic strip caused the crash was disputed during the trial both by witnesses (including the pilot of then French President Jacques Chirac's aircraft that had just landed on an adjacent runway when Flight 4590 caught fire) and by an independent French TV investigation that found a wheel spacer had not been installed in the left-side main gear and that the plane caught fire some 1,000 feet from where the metallic strip lay.

So German pilots held the initiative and could decide if they wanted to chase their opponents, could attack them from above and behind and then gain altitude for a new attack. Meanwhile, Polikarpovs could only defend each other by forming a defensive circle or via horizontal maneuverability. Moreover, in terms of armament, Messerschmitts had a slight edge on the I-16. The Emil carried two wing-mounted 20mm MG FF cannons and two synchronized 7.92 mm MG-17s with a weight of a one-second salvo of 2.37 kg, while the most common version of the I-16 – armed with just two synchronized and two wing-mounted 7.62 ShKAS – could deliver 1.43 kg of bullets each second.Drabkin 2007, pp. 142–43. Finally, the ammunition storage on a Messerschmitt exceeded that of the I-16, carrying 1,000 rounds for each machine gun (plus sixty drum-housed rounds for each cannon), while the Polikarpov carried just 450 rounds for each ShKAS gun.Drabkin 2007, p. 143. Around half of all produced I-16s were still in service in 1943, when they were finally replaced.
