I didn't even realize that F-102's were ever in Vietnam. I guess I never really thought about it, but early in the war they probably just tried what they had available to see what worked. That one looks like it's been cannibalized for just about every part available, even parts of the skin.
I've never seen any of the Century Series fly, and I regret that. I've seen a bunch on the ground but never in the air. Some of them were amazing machines for their day.
