Why would they have canceled it being so advantageous, cheap, light and maneuverable?
It couldn’t have been looks: the Super Crusader was a far sleeker aircraft than the pudgy Phantom.Perhaps it was economics as the Department of Defense in the early 1960s pushed for a common fighter for the Air Force, Navy and Marines.Safety might have had something to do with it, too: the Crusader I and II were known for high accident rates.Or was it because the Super Crusader was a hotshot dinosaur, a superb throwback to an earlier era of stick-and-rudder dogfights?For example, Sparrow missiles required painting the target with a radar beam.A Phantom pilot could leave this to his backseat weapons officer while he flew the plane.The pilot of a single-seat Super Crusader would have had to fly the plane and control the Sparrow.The Phantom was also more versatile, serving as a bomber, Wild Weasel air-defense killer and reconnaissance aircraft.In fact, the F-4 was so remarkably adaptable and tough that the last U.S. military Phantom wasn't retired until December 2016.For all the speed and maneuverability of the Super Crusader, it is doubtful whether it could have remained relevant for fifty-eight years.
It´s the FLASH GORDON 1937 spaceship
Technically, its the Dornier Do 31E.The one pictured is the second one built. That one had all ten engines fitted and made its first transition from vertical flight to horizontal flight on December 16th, 1967.
It is a Dornier Do 31. Is still the only transport VTOL ever.
