NTSB: Co-pilot of spaceship unlocked braking system early

[n2doc]

WASHINGTON (AP) — Federal safety investigators said Tuesday the crash of a Virgin Galactic spaceship last year was caused by a catastrophic structural failure triggered when the co-pilot unlocked the craft's braking system early.

National Transportation Safety Board investigators said the resulting aerodynamic forces caused the brakes to actually be applied without any further action by the crew. Investigators said no safeguards were built into system to overcome the error of the co-pilot.

The spaceship broke apart over the Mojave Desert during a test flight 10 months ago. The accident killed the co-pilot and seriously injured the pilot.

NTSB officials said early in the investigation that the co-pilot prematurely unlocked equipment designed to slow the descent of the spacecraft during initial re-entry. Simply unlocking the spacecraft's brakes shouldn't have applied them, but investigators had said that might have happened anyway and the resulting stress may have contributed to the spacecraft's destruction.

1. Why were no safeguard built-in?

Was it a madman, devil may care, roll the dice and take your chances on a shoestring thrill ride, or did they deliberately eliminate the safeguard to cut costs and show potential investors they were a potential goldmine?

2. Software error...the copilot unlocked the brakes in preparation and the computer deployed them...

This has been a very exciting program with innovative engineering. They've had a good safety record...we'll see what they find out but I for one am glad they're building another one.
