The pilot who survived the crash of the Virgin Galatic space plane says he managed to flash a thumbs-up to colleagues as he parachuted into the ­Mojave Desert, according to reports.

Peter Siebold’s dad visited the brave pilot Saturday at his California home, and quoted him saying that he blacked out during his 10-mile descent, but “I must have come to during the fall,” Britain’s Daily Mail reported.

“I remember waving to the chase plane and giving them the thumbs-up [as he dangled from a parachute] to tell them I was OK . . . “It’s a miracle I survived.’’

The Oct. 31 crash killed his close friend and co-pilot, Mike Alsbury.
