Air Force launches Double super secret space plane 1 day after delay
The Air Force has launched a second experimental space plane that resembles a small shuttle.
An Atlas 5 rocket blasted off with the unmanned space plane Saturday afternoon from Cape Canaveral. Air Force officials aren’t saying much about the X-37B orbital test vehicle. It’s the second of its type to be launched. The first rocketed into orbit last spring. It landed in California in December following a 270-day mission.
