That is correct, in the case of the ET accident Thrust was not reduced after takeoff and the aircraft managed to increase speed to 460kts before it contacted the ground.
The stall warning system had activated and possibly distracted both pilots.
I don’t mean to be blunt but after years of flying, both accidents could have been avoided in my humble opinion and pilot error was a major contributing factor in both accidents.
I do mean to be blunt - you have an opinion, as do others.
That may be startling, for a person of your experience. You have heard Captain Sully's opinion on this matter I assume.
Don't get me wrong both accidents could have been avoided, in fact I am yet to find an accident that could not have been avoided - more so with 20-20.
