Remember the Mach 20 aircraft that underwent testing a couple of weeks ago, only to have lost contact with it after a while? Well, it seems that DARPA, the Defense Advanced Research Projects Agency, has recorded a video of the HTV-2’s flight before it actually crashed due to safety issues. The whole idea of the HTV-2 when perfected would be to have it strike any part of the globe within a single hour.What you see in the video would be a speed comparison between DARPA’s HTV-2, a C-5 and an F-18, where the HTV-2 somewhat reminds me of Iron Man entering supersonic mode to shake off a couple of F-22 Raptors back in the first Iron Man movie that starred Robert Downey Jr.
