In January 1966, in an accident now known as the Palomares incident, a B28 nuclear bomb was lost off the coast of Palomares, Spain, after two United States Air Force aircraft of the Strategic Air Command (SAC), a B-52G Stratofortress bomber and a KC-135A Stratotanker aerial refueling aircraft, collided during aerial refueling. Brashear was serving aboard when it was dispatched to find and recover the missing bomb for the Air Force. The warhead was found after two and a half months of searching. For his service in helping to retrieve the bomb, Brashear was later awarded the Navy and Marine Corps Medal, the highest navy award for non-combat heroism.
