The planes are angle-parked with their engines facing outboard. How is McCain supposed to have flashed the plane astern of his?
No. 416 is McCain's, and the A-4 astern of him, no. 405, was Fred White's: the pilot who was most likely struck first by the rocket. That plane is not visible in the photo because it's engulfed in flames. McCain didn't cause White's plane to go up unless his ordnance was mounted sideways, and if he was the one responsible for the rocket firing, it would have been the F-4s on the starboard side of the fight deck that were struck, not White's and his own craft.
F-4 no. 110 (out of frame in the photo) is clearly properly aligned for a rocket to strike White's and McCain's A-4s. Dismissing an official report isn't rational when it lines up with the evidence.
