I am agreeing that THIS TIME, in THIS CONFIGURATION, McCain apparently could not have caused the fire in the other aircraft that lit off the Zuni.
It was his reputation for multiple incidents like that that WAS EARNED for starting such fires that caused the men on his ship to apparently have such disdain/hatred for him.
Probably not since the Zuni rocket came from an aircraft across the deck in his direction and was the initial cause of the fire.
