It was indeed a looker in my opinion.
I have a good friend who was a navigator on B-58's. Fast and fuel critical. Had the balloon ever gone up it was a one way mission he said. Recovery was to Turkey for most of their assigned targets.
He also said she was a nightmare to keep serviceable. The avionics were cutting edge and basically unreliable. He said if they needed the Vulcan gatling cannon in the tail she was a goner as they could not manoeuvre at speed too much.
