Actually in the Bagram crash it was an unbalanced load that caused the crash. On climbout under takeoff power a tracked armored vehicle that was improperly lashed broke free of it’s tiedowns shoving all the cargo behind it to the rear of the plane, a 40 ton weight shift. Obviously the plane did not “zoom” upwards even though it was under full power, it stalled immediately and the result was catastrophic. This lends evidence to your scenario.

According to the NTSB the cargo shift occurred at rotation. The aircraft did fly and gain altitude until it stalled. Swordmaker claimed an unbalanced aircraft with a rearward shift in the center of gravity can’t fly or gain altitude. I offered the video as a counterexample.
