The Turkish Airlines Flight 981, a McDonnell Douglas DC-10, crashed in a forest northeast of Paris, France On March 3, 1974. The London-bound plane crashed shortly after taking off from Orly airport. All 346 people on board died. It was later determined that the cargo door detached, which caused an explosive decompression; this caused the floor just above to collapse. The collapsed floor severed the control cables, which left the pilots without control of the elevators, the rudder, and the second engine. The plane entered a steep dive and crashed. It is currently the deadliest single-aircraft crash with no survivors.
Mercury also wrote six songs from Queen II which deal with multiple key changes and complex material. "Crazy Little Thing Called Love", on the other hand, contains only a few chords. Although Mercury often wrote very intricate harmonies, he claimed that he could barely read music.
