The aircraft was named after Evette Branson, the mother of Richard Branson, Chairman of the Virgin Group. The jet plane has nose art of a blonde woman holding a banner with the Virgin Galactic logo.[3] The image is based on how Evette Branson looked when she was younger and is called Galactic Girl.[4] The aircraft was officially launched on July 28, 2008, in Mojave, California, the United States, at the Mojave Spaceport, home of Scaled Composites. On December 12, 2008, the aircraft performed first taxi tests,[5] and a week later the maiden flight.[6] Eve was used in the Virgin Galactic testflight program before entry into commercial usage.[7]

Burt Rutan has dismissed fears that pressurization cycles might induce fatigue failure in the composite structure.[8] Richard Branson has also announced that it will be highly fuel efficient.[9]

Flight test program

The initial flight occurred on 21 December 2008, after an initial low speed taxi test was carried out at Mojave[10] followed by a high speed taxi on 16 December.[11] By September 2009 the flight envelope was extended to 50000 feet.[12] As of 19 September 2014 the total flight time for WhiteKnightTwo was 333.96 hours.
