"We're in a testing phase, and things happen," says Jim Clash, an adventure journalist who put down a $20,000 deposit on his $200,000 ticket in 2010. (Prices for tickets have since risen to $250,000.)
Clash has no plans to cancel. "I've done a lot of the things I've wanted to do on my bucket list, but space is something I haven't done," he says. "And I really want to do it."
SpaceShipTwo doesn't travel all the way into orbit. It's designed to rocket just to the edge of space and then float back to Earth. Passengers get a couple of minutes of weightlessness and one heck of a view. That was enough to get hundreds of people to sign up.
Since the accident, Virgin Galactic reports that 20 or so ticket holders have asked for refunds. Among them, the U.K.'s Princess Beatrice, according to media reports.
"That doesn't surprise me. I think there's a group, actually, that bought the tickets because they're fashionable," says Clash.
But more serious ticket holders seem to be hanging on, at least for now.
"We think that this is going to be a very productive area across the 2010s and into the 2020s for research applications," says Alan Stern, an associate vice president with the Southwest Research Institute, a nonprofit research institute based in Texas. The institute has bought a total of nine seats on future flights for its own experiments. "We want to be out front," Stern says.
Both Clash and Stern say they expected setbacks when they purchased their tickets. "Just like the early airlines and the early jet age, there will be some bumps along the road," Stern says.
And despite the fact the NTSB investigation could take up to a year (and the fact that SpaceShipTwo's replacement isn't yet ready to fly), Clash doesn't see himself canceling his ticket.
"I'm willing to wait as long as it takes," he says.
