Operation Eagle Claw, known as Operation Tabas (Persian: عملیات طبس) in Iran, was a failed operation by the United States Armed Forces ordered by U.S. President Jimmy Carter to attempt the rescue of 52 embassy staff held captive at the Embassy of the United States, Tehran on 24 April 1980. As the U.S. forces prepared to withdraw from Desert One, one of the remaining helicopters crashed into a transport aircraft that contained both servicemen and jet fuel. The resulting fire destroyed both aircraft and killed eight servicemen.
