What's up with these planes?

Yes, I fit the "old guy" description very well!

Though I was on a tactical missile launch crew, my barracks window in Germany overlooked an earth covered revetment that protected an F-102 of the 496th FIS. Late night engine runs would guarantee either getting up to watch the glowing tailpipe, or pulling the pillow over my head to help block out the scream. You couldn't just ignore it.

I wonder if the TSGT who submitted the idea for a tail insignia was indeed a Chrysler fan? The fact that the 318 engine came out in '57, the year the insignia was picked, and that the squadron number was 318 might not have been a coincidence.
Very likely! Mopars were big with the AF guys. Most of the muscle cars in the lot were Mopars. I was at Minot in 71' and the F-106 Hangar was right next to the Helicopter hangar, where I was assigned. UH-1F, missile support. Those Norad Jets were a spectacle! With taxiing B-52's nearby, the noise permeated your body. Esspecially at -30 degrees! Omaha was never cold to me again, after 18 months up there.
