Turkish airliner crashes at Schiphol
I would like to add to my previous post :
How the crew allowed this aircraft to enter this Undesired Aircraft State is what we are trying to understand, not to judge, but never to repeat.
Personally, Flight Safety's,sterile cockpit, below 10,000" should always be applied ( even and especially on Training flights, and whatever mistakes be explained on the ground ). This will give the crew all the time to Aviate ( Fly the aircraft ), Navigate, then Communicate.
