At 4 Oct 1992 around 19:00 local time a 747-200 crashed into a block of flats after losing both engines on one side.
Number of casualties was set at 43, but that number is still disputed.
The aircraft already had engine mount prolems week before the crash (oil leaks at the mounting pin location), and was hated by the crews because of the bad suspension. A few months before the crash, the roof panel fell down after a landing in New York.
The most disputed thing about this crash is the cargo, still not much known about what really was in there.
