Virgin Galactic Founder predicts SpaceShipTwo would be ready to fly in 12 months. A year after that — March 2009 — the vehicle would begin commercial suborbital space flights.
The reality is that in 2007 they didn’t have an engine capable of firing for the one minute needed to send SpaceShipTwo above 50 miles. They weren’t even close to having one. It would take another 7.5 years to develop one they would even risk firing for more than 20 seconds in flight.
SpaceShipTwo VSS Enterprise was destroyed on Oct. 31, 2014 during the flight during which they were supposed to test that engine. That accident set the program back by another five years.
