This is a video clip of the world record 8,000 mile flight by the B-58 in 8 hours, 21 minutes. My crew did not fly the mission but we conceived and planned it. (Not photogenic enough). The video is not too smooth (on my computer) but summarizes the flight pretty well. If I remember, there were five in-flight refuelings where the B-58 throttled back from Mach 2, descended from 50,000 feet altitude to 25,000, joined up with an airborne tanker aircraft, topped off fuel tanks, and again accelerated to Mach 2 and 50,000 feet. The last post-refueling leg, the crew flew at subsonic speed (about 600 miles an hour) after the afterburner failed to light on the outside starboard engine. The original flight plan we developed could have flown the 8,000 miles in 7 hours.
