The Credible Sport operation was a new plan to rescue the hostages after the dramatic failure of Operation Eagle Claw. Eagle Claw failed when a C-130 Hercules and a Sea Stallion helicopter collided in the Iranian desert, killing 8 servicemen. Credible Sport was abandoned after the election of Ronald Reagan as President in November, 1980.
The Credible Sport plan called for highly modified C-130 Hercules cargo planes to land in a soccer stadium not far from the American Embassy in Tehran and airlift the hostages out. Three aircraft were modified under a top secret project at Eglin Air Force Base, Florida to YMC-130H configuration with rocket packages blistered onto the forward and aft fuselage, which theoretically enabled the planes to land and take off within the confines of the sports arena.
