Dear Borage, "Pugachev Cobra" is first performed by Russian pilot Victor Pugachev at Paris Le Bourget Air Show at 1989. This is written in all aviation the Internet sites and encyclopedias of all World.But your nonsense has no any proofs. This Swedish plane small and old. Probably it did similar manoeuvres when collapsed in flight. Only modernmaterials and technologies have allowed to do it safely and effective.

SAAB J 35 Draken (Dragon) from 1955 was the first fighter to perform the cobra maneuver.

The maneuver consists of the pilot disengaging the alpha limiter and pulling the aircraft to a 90°--120° angle of attack, then back down to zero. In a properly performed Pugachev's Cobra, the plane maintains a straight and level flight throughout the maneuver.

Thrust vectoring aircraft (such as the Su-30 'Flanker', Su-37 'Flanker-F', Su-47 'Berkut', MiG 1.42, F-15 ACTIVE, F-16 MATV/VISTA, and NASA's X-31) should be able to perform this maneuver more easily, though note that the air intake still needs to be able to handle the air inflow. Russian fighters, designed for high maneuverability, are known for performing this maneuver at air shows for dramatic effect.

Vehicles known to be able to make the cobra maneuver are the Su-27 'Flanker' family (from horizontal flight), MiG-29 'Fulcrum' (from a 30 degree up angle), the F-22 (from horizontal flight) and the F/A-18E/F (from horizontal flight).

The "Pugachev Cobra" is a fighter aircraft maneuver. The maneuver is so named after the Sukhoi OKB (design bureau) test pilot Viktor Pugachev, who first performed the maneuver at 1989 on SU-27.Maneuvers that are related to it include the Cobra Turn, and the Frolov Chakra.

DO remember that the cobra can be performed by Su-27 that doesn't have thrust vectoring.
pavelpopov (November 30, 1999 at 12:00 am)
Yes, now the some planes can do. The thrust-vectoring nozzles equipped and very strong body is necessary. But SU-27 Family is the best! The titan and the perfect construction.

it is thought that EU and US planes can now do the Cobra, as long as there are thrust-vectoring nozzles equipped. |
