Quote from Lucrum:
It was concluded later that the cargo broke lose and shifted aft, moving the aircraft's center of gravity with it of course. With excessive aft CG the nose pitches up uncontrollably, the wings exceed the critical angle of attack, stall and the nose then drops sharply. In this case all at very low altitude. There was nothing the pilots could have done.
I understood about half of that. Lol And no wonder smaller commercial flights I've been on would move passengers to even center of gravity. When the pilot has the flight crew ask for volunteers to move, I always say point me to the seat you need filled.
Sad to see those guys go like that. I'm sure they knew they were done when the nose pitched like it did. I can't imagine...
