According to Virgin Galactic:
“SpaceShipTwo achieved another successful first today with a spectacular “Cold Flow” flight. The test objectives were successfully met, advancing another important step towards powered flight.
In preparation for SpaceShipTwo’s first powered flight, the test teams from Scaled Composites and Virgin Galactic completed the profile of the upcoming milestone flight – apart from actually igniting the rocket. Importantly, and for the first time in the air, oxidizer was flowed through the propulsion system and out through the nozzle at the rear of the vehicle– thus successfully accomplishing the “Cold-Flow” procedure.”
