Virgin Galactic's test space flight cut short after motor failure
Richard Branson's space tourism company Virgin Galactic on Saturday cut short a test suborbital flight of its SpaceShipTwo Unity plane, after the rocket motor’s ignition sequence didn't complete. The flight's pilots safely returned to Spaceport America in New Mexico. Virgin Galactic aims to start flying commercial passengers to space in 2021, with Branson also expected to take a flight.
