Convair was a big believer in the delta wing concept, witnessed by not just the B-58, but the F-102 and F-106 Daggers. and Darts. Convair was a big-time subcontractor to McDonnell Douglas and built much of the Atlas boosters for NASA during the race to the moon. And how can we forget the notorious Pogo? Good company until General Dynamics ate them. NB when I was a lad, I remember getting a plastic model of the B-58 Hustler for 50 cents and some cereal box tops. Loved that model.
