Pete Siebold and Mike Alsbury heard the sound of hooks disengaging and felt a sharp jolt as SpaceShipTwo was released from its WhiteKnightTwo mother ship. Relieved of a giant weight, WhiteKnightTwo shot upward as the spacecraft plunged toward the desert floor.
“Fire,” Siebold said as the shadow of one of WhiteKnightTwo’s wings passed across the cabin.
“Arm,” Alsbury responded. “Fire.”
The pilots were pushed back into their seats as SpaceShipTwo’s nylon-nitrous oxide hybrid engine ignited behind them, sending the ship soaring skyward on a pillar of flames.
