It appears the engine is spooling up between pic 10 and pic 11. Not in AB, but not at idle either.
It is a multi-million dollar screw up, pilot error.
In the amount of time that elapsed between pic 10 and 11, a turbine engine cannot spool up very much. When it start sucking in prime Wisconson turf, however, it can spool down rather quickly (and permanently...)
That is interesting, I didn’t see that before. With the deceleration and gear collapsing, maybe the pilot hit the throttle with his hand or arm while being thrown forward, because the nozzle does close down between 10 and 11. Just a thought.
