Could an experienced pilot recover from this?
It looks like they have some altitude, that could've been converted to speed, but it is hard to say for sure from this angle. I believe there is a stall warning system installed on this plane. Something got terrible wrong.
I'm not sure if it is still common practice but I thought that military or contract cargo ops usually state that in a conflict zone a higher angle of attack departure is used to get out of range of small arms fire etc. Cargo shift as a result or contributor or run away trim any number of things meant for a bad day. May they rest in peace.
I've had a runaway electric trim on takeoff before. The switch on the yoke broke. Got my attention for sure.
