Hey folks, I've been lurking on this forum on and off for a few years and got the opportunity to sign up last week. I've mostly been looking at the scifi studio-scale stuff, but this thread caught my eye. If anyone is interested in reference photography of the SV-5J (Martin-Marietta's jet-powered X-24A variation that never flew; supposedly the dimensions are the same as the original X-24A, AKA SV-5P, save for the jet intake on the bottom), Martin-Marietta donated one to the Air Force Academy in 1980. The other SV-5J was converted to look like an SV-5P and lives at Wright-Pat.
I'm on exchange at West Point this semester, but I'd be happy to take some photos when I return to Air Force in January. I seriously walk by the thing every day on the way to the Aeronautics Lab. Direct measurement with a tape measure would be difficult as it's mounted about ten feet off the ground, but some trig should solve that. Or I could try rigging up something with laser pointers.
