I have in the back of my mind a DC8F crash caused by a rock/stone (?) jammed between the elevator/Stab during taxy-out control checks due "FOD" by the engines. On departure they could pull back, but not push forward.
Years ago my F-4 squadron lost a F-4 that tried to fly straight up just after takeoff. Fortunately those guys ejected, although one was injured due to a seat malfunction.
It turned out that during depot maintenance a wrench had been left in the tail cone and glued in place for a year by that yellow anti-corrosion paint. The wrench got lose and jammed in such a way that the pilot could pull back on the stick, but not forward.
That's why when I saw this horrible video my first thought was some sort of flight control malfunction.
