some time for the space travelers and pilots to get to know each other. the aircraft will set off attached to a mother ship, which will climb to 50,000 feet before detaching. then the enterprises rocket motors will ignite, accelerating the ship to three times the speed of sound, taking it up over the earths atmosphere. at that point, the engines will shut off, leaving passengers weightless, able to tumble freely, and, most importantly, see earth from space. “thats the point when the switch flicks,“ says attenborough, ceo of virgin galactic. “you get an understanding of the fragility of
