turboplanner Posted April 21, 2012 Share Posted April 21, 2012 This analysis is good news, and makes sense. The CIA A-12 Oxcart/USAF SR71 Blackbird had a thick titanium skin which was still at around 600 Deg F on the ground after just Mach 3 cruise. So we know the power unit design works, and the skin technology is the next hurdle which I'm sure fertile minds will find a solution to Link to comment Share on other sites More sharing options...

turboplanner Posted April 22, 2012 Share Posted April 22, 2012 It would be a case of "What Gazelle?" Neil, the Oxcart landed so fast it needed an enormous runway. In the finish they'd run it out on to a dry lake and round a big circle. If you go to Google Earth and search for Area 51 the runway complex comes up If you zoom in "Groom Dry Lake" comes up. It's the right runway, RWY 32R I see the other one has crosses on it. Link to comment Share on other sites More sharing options...
Guest pookemon Posted April 22, 2012 Share Posted April 22, 2012 It should be flying a much, much wider and higher circuit than the gazelle. :) Link to comment Share on other sites More sharing options...
