An historic HFL Kholod Mach 6.47 scramjet jointly developed by NASA and CIAM -- the fastest rocket ever built -- is going under the hammer in September.
When you wish you had an extra pair of hands, two extra robot fingers could be enough. Also, the "holy grail of comic books" is up for grabs!
The accomplishment marks the longest flight for the $300 million X-51A technology demonstration program and, according to the Air Force and Boeing, the longest scramjet-powered hypersonic flight ever.
Over at the Skunk Works, aircraft designers are hard at work cooking up a hypersonic scion to the legendary SR-71, the superspeedy recon jet of the Cold War.
Trouble with a control fin on the sleek, scramjet-powered aircraft puts an abrupt and early end to the Air Force's attempt at a Mach 6 flight.
The flight failed due to aerodynamic problems caused when a fin became unlocked, sending the experimental aircraft into a corkscrew. A fourth X-51A flight will likely take place next year.
The new XS-1 program wants designs for satellite-toting flying machines that are fast (hypersonic, even), cheap, and reusable -- on a one-day turnaround, no less.
The Air Force's experimental, scramjet-powered Waverider makes a short but historic flight in a test range over the Pacific Ocean.
X-51A WaveRider scheduled to be dropped over Pacific Ocean in December inaugural test flight.
