Plus they had bad hydralics. I mentioned elsewhere that one evening I watched an F-102 fly by just over the treetops cockpit lights on, and I could see the pilot working on something in there. Very low, very slow. It was out of the Weat Hampton Air Base.
Next day I heard that the pilot had died, he waited, doing what he could, until the jet was almost over the Ocean and punched out, the 'chute opened, but when he hit the South Bay, he could not get free of the 'chute and drowned. Yes, the F-102 was a pretty delta wing to see in the air, but had a very bad reputation concerning reliability.
