Yeah, I saw that thread. But I thought it might be prudent to stick this one out by it's lonesome since there is a name with a summary and rank. :) (ie: Other than media dawgs)
If indeed the pilots were seen doubled up, me wonders if there was some kind of nerve agent release in the cockpit that would cause muscular spasms enough to distort the bodies shape enough to be noticed by the f 16 pilots. Whack the cock pit fast enough and the plane is screwed.
