out the pilot noticed they were rapidly approaching the base of the low cloud and in an attempt to prevent the aircraft entering the cloud (and so not being visible to the spectators on the ground) he pushed the control column hard forward to arrest the ascent and commence a shallow descent. This caused sudden negative G which caused all four engines to flame out due to temporary fuel starvation. In an attempt to re-start the engines he then had to drive sufficient airflow through the engines which could only be done in a dive. While in a dive and attempting to re-start the engines the flight crew were preoccupied with the engine re-start until the pilot looked out of the windscreen and saw how low they were. He pulled back hard on the control column and thereby exceeded the airframe strength limit and the aircraft broke up

After reaching an altitude of about 3,000 feet the PIC tried to bring the nose down coming to a level flight. For that he tried a full AND (A_irplane N_ose D_own) and he retracted the canards (the canards would be torned off, if extracted at higher speed to be reached on level flight some moments later) at the same time, violating the sequence given in the manual. Obviously he tried (or was driven to do so) this to impress the audience. Until this moment the flight control system had suppressed the maximum AND to -5 degrees of the

When there is an official investigation report that concludes to a last minute technical modification that allowed flight parameters to be exceeded, combined with improper actions from the crew (wasted time with a camera that fell in the cockpit, extension of canards outside of their operation parameters which broke and punctured a wing and a fuel tank). The conclusions of the investigation are also consistent with the footage from the accident and ocular witnesses.

to photograph the TU-144 in flight. In particular, the French wanted detailed film of the canards, the insect wings behind the cockpit. Flying at a height of approximately 4,000 feet in and out of the clouds, the Mirage tracked the TU-144 through its routine. As the Soviet plane climbed on a trajectory which would cross the Mirage's flight path, the pilot, Koslov, was not aware that the French jet was flying directly above him."

The article over-emphasizes the unsubstantiated "Mirage" theory because it's controversial (industrial espionnage) despite not having any reliable source (besides a TV show named NOVA and a times.com story) and even tries to justify it saying "French and Soviet governments colluded with each other to

What the crew did now, could have possibly saved them, the lives of eight others on the ground, and the jet, if they wouldn't overdo this action. The pilot tried to pull out the plane of the

The most plausible explanation for the accident is that in an attempt to outdo the previous
Concorde display (which had involved a very steep climb out from the runway) the Tu-144 pilot did the same but did not allow for the low ceiling of the cloud base which had developed. During the steep climb

In a PBS Nova show some years ago, the suggestion was made that in response to seeing the Mirage, the Tu-144 pilots might have made a maneuver that caused engine flame-out. That the fix for such flame-out in flight is a steep dive to get enough air though the engines to restart them. I only know

The Mirage theory relies on the source that says "The full report from a French-Soviet investigation was never disclosed. At the time, there were rumors of a botched espionage attempt by the French, mistakes by the crew, and mechanical failures." However, the report has been disclosed since, and

Is there evidence that there was, or was not, a flame-out before crash? There are enough stories about engine flame-out with unusual flight conditions. As I understand it, the best recovery is a dive to get enough air through the engines, to restart them.
