What I'm seeing is: tipstall, recover, pull too hard and tipstall again, almost recover before runnning out of altitude and ideas. I've done it with one of my RC planes that had a nasty stall characteristic. I would have expected, with a state-of-the-art Fly By Wire control system, this would not have occurred. Sadly I did not see a parachute.

This time, he pulls it all together. Tactically, if you spend a lot of time at zero airspeed flying backwards, some reservist is gonna circle around with an F-16 and perforate you thoroughly. www.crazyaviation.com/movies/CA_SU-30.wmv |

Bit of an update here. Incredibly, both pilots survived this crash. The story is that they ejected once they hit the ground and the last still photo in the attached link does show both chutes in the air. There may have been a mechanical malfunction as well but the reports say that both pilots got prison time because about 84 people died. www.aviapedia.com/video/su-27-crash-in-lvov-videoI was at Laguna Seca racetrack in Monterey, CA back in the mid nineties with a friend and his wife. The friend, Jack Ward, had given Michael Andretti's lead mechanic a ride in Joe Kasparoff's P-51 a couple of weeks previously, hence the invite. Salinas airport is only a few miles away and Monterey airport is only a few blocks away so the racetrack was completely within what was called at the time Monterey's "airport traffic area" and therefore its airspace was under the direct control of Monterey's tower. At that time there was a Mig-29 touring the U.S. and actually giving rides to anyone able to come up with the rather steep price of a ticket, which I believe was on the order of about ten grand. During the race this MiG showed up and did a low level airshow directly over the crowd, no standard 1500' deadline to keep the airplane away from the people but directly over the crowd. I vividly remember watching a vertical climb and tail slide so exactly over my head that I could watch the afterburner nozzles on the engines scheduling open and closed until the airplane ran out of forward momentum and the view changed to one of the exact front of the airplane coming at me after it pitched over from vertically up to vertically down. A Piper Pawnee towing a banner showed up in the middle of this impromptu routine and started circling the racecourse while honking an air horn stuck out the cockpit window. He was then nearly center-punched by the MiG, which was executing a high speed north to south pass over the crowd (right through the final approach course to Monterey's only runway) at the time and which only missed him by a couple of feet as he made a quick porpoise-like correction to go over the Pawnee. Interestingly enough, the Mig had done the same airshow over the crowd the previous day, Saturday, as well. Neither of these yahoos was given permission to 1.) operate within Monterey's Airport traffic area or, 2.) in the case of the MiG, do aerobatics over a crowd of several thousand people without any of the normal safeguards associated with such routines. (FAA rules for operating aircraft over large crowds pretty much tightened up back in the fifties after an F-89 ended up in the stands at an airshow.) Guess they do it differently over there. |

I note that the airplane in the other video that was doing all the ultra-high alpha maneuvering was an Su-30 equipped with canards while the one that went in was a garden variety Su-27 which does not have those canards and their attendant electronic wizardry.
Practicalities of such maneuvers as the Cobra or actually being able to fly backwards as the subject Su-30 does after a 45 degree plus angle of attack loop aside, it is pretty obvious that Sukhoi really has their act together when it comes to fighter aerodynamics.
There is also the fact that a lot of the maneuvering shown is not done in normal flying and is only possible by disabling certain alpha and G limiting devices for the express purpose of doing these radical maneuvers.
Whatever sells airplanes...
