Believe the wings had a habit of falling off in the early days! It was pretty much McManure’s AF version of the Edsel.
Yeah, weren’t the swing-wing actuator mechanisms in the F-111’s ballscrew and nut assemblies? The F-14s had them too but they didn’t have that problem or did they? I’ve never heard of any problems with the wings of the B-1B, the largest variable geometry-winged military aircraft ever produced.
