In 1991, Israel evacuated 14325 Ethiopian Jews in 36 hours using 35 aircraft, with up to 1122 passengers on a plane [1]. It's such an impressive feat, those must have been some of the best pilots, to be able to fly such an overcrowded plane (even though they stripped the seats from the planes it was probably still overloaded)
