XCOR's Lynx Will Travel 62 Miles Above the Ground at Mach 3.5

Test flights scheduled for early 2013


Since the last flight of the Concorde in 2003, supersonic travel has been the province of jet fighter pilots and Felix Baumgartner.

XCOR Aerospace wants to change that. Out of a group of outfits looking to bring back travel faster than the speed of sound, it has an especially intriguing idea: flying from one airport to another, via outer space.
