a hundred people in Germany board on a charter flight to New York
Hmmm, given that the accident occurred out of CDG, if this is indicative of the standard of "investigation" it should make for interesting viewing.
Concorde Accident Includes links to all reports, including this one, the official
BEA Report.
This report states that V1 was 150kt, VR 198kt and V2 220kt. Actual rotation, however, was at 183kt and maximum achieved airspeed was 211kt, although it was little above 200kt for most of the time airborne. The zero rate of climb airspeed (Vzrc) was calculated as 205kt with one engine failed and gear down.
The report goes on to state
The crew had no way of grasping the overall reality of the situation. They reacted instinctively when they perceived an extremely serious but unknown situation, which they were evaluating by way of their sensory perceptions. Each time the situation allowed they applied the established procedures in a professional way.
The gear wouldn't come up because of a problem in the gear logic circuit either associated with damage to, or the absence of, the left hand main gear door. Thrust output from engines 1 and 2 was varying wildly from as much as 80% to as little as 3% nominal thrust. This was identified in the report as being due to, for engine number 1 the ingestion of tyre debris or hot gases, and for engine number two, hot gases alone. The entire sequence from the first loss of thrust to the impact took some 40 seconds.
It also states that a rejected takeoff, had the crew grasped the seriousness of the situation, would have resulted in a high speed overrun and, given the fire that was already burning, it is very likely that the aircraft would have been destroyed by fire very rapidly.
It states further that even had all four engines been operating normally, the damage caused by the fire to the wing structure and control surfaces of the aeroplane would have led to a loss of control.
In essence, these poor people were doomed as soon as the fire started.
