I think the answer is that both don't have websites designed for people doing research beyond "what's the cafe menu?" I've been physically to both museums and the USAF museum is truly breathtaking. The Museum of Flight is far less so. I think civilian flying platforms, without some sort of modern fail-safe stability augmentation, would be a regulatory and liability nightmare. Plus the costs would be crazy, if not to buy and operate, to maintain. Zero-timing a jet engine is not a small expense and it's continual. P.S. My nom-de-HN is a tribute to a defunct project's code name. It was a sausage with a thin skin of delusion well stuffed with bad judgment and strongly seasoned with incompetence. Not to my taste at all. P.P.S. There seems to be a lot more info under "WASP" than "X-jet".
