NW B-727 accident out of JFK in December 1974.
Another classic case in failure to unload the wings, the pitch in this case was actually quite pronounced nose down, but since the FPA was almost straight down, the aircraft remained stalled, and in the end, the horizontal stab failed structurally, and the aircraft crashed...airspeed unreliable was also the initial cause of this accident...(frozen pitots)
