They got as far as the contrails before calling the whole thing off this morning.
As happens in the minutes before each SpaceShipTwo flight, twin contrails appeared behind the WhiteKnightTwo mother ship.
The contrails cut across a clear blue Mojave sky on an otherwise perfect day to fly. There were neither clouds to obstruct the view nor the high surface winds at the Mojave Air and Space Port that caused the scrub of a drop test on Tuesday. Conditions on the ground were calm and a lot warmer than they were two days ago.
Despite the perfect weather, observers on the ground did not see the separation of the smaller spacecraft from the dual fuselage carrier plane. Instead, the pair headed back to base.
Virgin Galactic tweeted that they needed to look at something. It’s not clear what that is, or when they will attempt another flight.
The mated vehicles are now safely back on the ramp.
