July 31, 1973
Boston, Massachusetts
Delta Airlines Flight 723 crashes, killing all 89 occupants

Weather conditions including fog, as well as a controller busy handling a potential collision between 2 other aircrafts, were the main causes for the fatal crash. While attempting to land, Flight 723 struck a seawall which demolished the craft. Two of the 89 occupants initially survived the crash but later died from their injuries, one within hours and the other in December of 1973.
