English: Eighty days after it fell into the ocean following the January 1966 midair collision between a nuclear-armed B-52G bomber and a KC-135 refueling tanker over Palomares, Spain, this B28FI nuclear bomb was recovered from 2,850 feet (869 meters) of water and lifted aboard the USS Petrel (note the missing tail fins and badly dented "false nose"). This photograph was among the first ever published of a U.S. hydrogen bomb. Left to right are Sr. Don Antonio Velilla Manteca, chief of the Spanish Nuclear Energy Board in Palomares; Brigadier General Arturo Montel Touzet, Spanish coordinator for the search and recovery operation; Rear Admiral William S. Guest, commander of U.S. Navy Task Force 65; and Major General Delmar E. Wilson, commander of the Sixteenth Air Force. The B28 had a maximum yield of 1.45 megatons.
