After flying low and fast over Spain, McCain returned to the USS Intrepid with ten feet of Spanish power line dangling from his airplane, which also had a severed oil line. The Spanish were not pleased.
I am reminded of the Cavalese cable car disaster of 1998, in which an EA-6B Prowler doing 540 mph at an altitude of between 260 and 330 feet severed a cable car cable, killing 20 people.
If memory serves, the pilot responsible for that incident was turned over to the Italians for trial, and was imprisoned as a result.
I don't think McCain's incident was quite as serious, but it still would have ended an ordinary naval airman's career.
