1980: Eight U.S. servicemen die in Operation Eagle Claw, an aborted attempt to end the Iran hostage crisis. After only five of eight helicopters made it to the first staging area in the desert of Iran, President Jimmy Carter granted the commanders' request to abort the mission. As troops prepared to leave, one of the helicopters crashed into a transport aircraft containing both servicemen and jet fuel, resulting in a deadly explosion and fire.
