Crashed 5 jets, plus was responsible for the Forrestal fire. Surviving crewmen and those who investigated the Forrestal fire case reported that McCain deliberately 'wet-started' his A-4E Skyhawk to shake up the guy in the F-4 Phantom behind his A-4. 'Wet-starts', done either deliberately (the starter motor switch allowed kerosene to pool in the engine and give a wet start) or accidentally, shoot a large flame from the tail of the aircraft. In McCain's case, the 'wet-start' 'cooked off' and launched the M34 Zuni rocket from the rear F-4 that punctured the Skyhawk's fueltank, knocked the M-65 1000 lb bomb off it's 500 lb rated mount, and touched off the explosions and massive fire. The F-4 pilot was reportedly killed in the conflagration, along with 167 of his fellow Forrestal shipmates (including those who died later from wounds suffered). 'Wet starting' was a common practice among young 'hot-dog' pilots. McCain was quickly (they were still counting the Forrestal dead) transferred to the USS Oriskany (the only Forrestal crewman to be immediately transferred).
