Some time this year, Sir Richard Branson promises, tourists will start taking off in Virgin Galactic SpaceshipTwo. Having paid either £125,000 (the early bookers) or £155,000, they can expect a two-hour trip that includes five minutes of weightlessness. What they can’t expect, according to a revealing piece by Jon Ronson in Guardian Weekend, is anything in the way of in-flight services or even access to a lavatory. “Every passenger will be required to wear a special astronaut nappy, or maximum-absorbency garment, under his or her flight suit, which hasn’t yet been designed.”
