WASHINGTON (AP) -- The pilot of a Virgin Galactic spaceship that disintegrated midflight recalls trying in vain to activate oxygen to help him breathe as he fell toward the California desert. Federal accident investigators on Tuesday released a summary of their interview with Peter Siebold, who survived when SpaceShipTwo ripped to pieces during an October test mission. The mission was part of nascent efforts to create a space tourism industry.
