On Jan. 17, 1966, James Milata was stationed at the Moron Air Force Base in Seville, Spain when he received the news that a B-52 bomber carrying four hydrogen bombs collided with a KC-135 refueling tanker in mid-air, scattering four h-bombs across the Spanish countryside near Palomares and one in the Mediterranean. The bombs were the Mk28 type, the smallest version of which carried a 70 kiloton warhead, which is nearly five times the strength of the bomb dropped on Hiroshima. Only the non-nuclear material exploded in two of the bombs, but the incident resulted in plutonium contamination covering less than a square mile. This was, perhaps, the most significant event Milata said he participated in during his 20 year enlistment with the Air Force.
