Virgin Galactic's SpaceShipTwo Crashes: 1 Dead, 1 Injured

This test flight was the first for a new kind of fuel-a plastic similar to nylon. Previously, SpaceShipTwo had used a synthetic rubber fuel, one that had been giving engineers trouble for years as they tried to scale up the successful 3-seat SpaceShipOne prototype, which won the X Prize in 2004, to a much bigger vehicle using the same hybrid rocket design and fuel, and meant to carry tourists to suborbital space.
We're left to wonder what impact the accident will have on the nascent commercial spaceflight industry, which Branson has been working hard to characterize as safe. Friday's crash is a stark reminder that spaceflight is an inherently risky endeavor.
