What The New Yorker Gets Wrong About the SpaceShipTwo Accident

Psychologists have identified five stages of grief: denial, anger, bargaining, depression and acceptance. These stages are clearly on display in Virgin Galactic’s Rocket Man, Nicholas Schmidle’s profile of Mark Stucky in The New Yorker. A substantial part of the story chronicles how the test pilot dealt with the death of his close friend, Mike Alsbury, in the breakup of SpaceShipTwo Enterprise during the vehicle’s fourth powered flight four years ago.

It’s a touching portrait of Stucky’s grief for his fellow Scaled Composites pilot, with whom he had flown while testing the suborbital spacecraft being developed for Richard Branson’s Virgin Galactic. (Stucky later moved over to Virgin, which took over the SpaceShipTwo program after the accident, to test the second SpaceShipTwo, Unity.)

However, Schmidle tells only half the story in his otherwise insightful profile. He places nearly all the blame on Alsbury, while ignoring the findings of a nine-month federal investigation that identified systemic flaws in the development program and the government’s oversight that contributed to the accident.

It’s similar to the flawed, self-serving narrative that Branson used in his latest autobiography, “Finding My Virginity,” complete with a not-entirely-fair jab at the press coverage of the crash. The billionaire uses pilot error to obscure a decade of fatal mistakes and miscalculations.

On the morning of Oct. 31, 2014, a nightmarish vision that had haunted me for months became a real-life disaster in the skies over the Mojave Desert. SpaceShipTwo dropped from its WhiteKnightTwo mother ship, lit its engine and appeared to explode. Pieces of the space plane then began to rain down all over the desert.

The motor had exploded. Or the nitrous oxide tank had burst. At least that’s what I and two photographers – whose pictures of the accident would soon be seen around the world – thought had occurred as we watched the flight from Jawbone Station about 20 miles north of Mojave.

We really believed we had seen and heard a blast nine miles overhead, the photos appeared to show one, and it was the most plausible explanation at the time.

We were wrong. More than two days after the accident, the National Transportation Safety Board (NTSB) revealed that co-pilot Mike Alsbury had prematurely unlocked SpaceShipTwo’s feather system during powered ascent. The ship hadn’t blown up, it had broken up as the twin tail booms reconfigured the vehicle with the engine still burning at full thrust.

In his new book, Richard Branson recounts that on the morning of Oct. 31, 2014, he was on his private Caribbean island in a state of “schoolboy excitement.” The reason? Three time zones away in California’s Mojave Desert, Virgin Galactic and Scaled Composites were conducting the longest and most ambitious flight test of the SpaceShipTwo suborbital tourism vehicle.

One day in mid-2003, Virgin Atlantic pilot Alex Tai wandered into a hangar at Mojave Airport and discovered SpaceShipOne, a  suborbital rocket plane that Scaled Composites’ Founder Burt Rutan was secretly building to win the $10 million Ansari X Prize for the first privately-built crewed vehicle to reach space twice in two weeks.

The chance discovery would eventually solve separate problems the famed aircraft designer and Tai’s boss, Richard Branson, were trying to solve. Rutan’s spaceship was being funded by Microsoft billionaire Paul Allen, who wanted to win the prize but had no plans to finance a commercial follow-on spacecraft.

Four years earlier, Branson had registered a new company named Virgin Galactic Airways and set off in search of someone to build a vehicle capable of carrying passengers into space. Those efforts had come to naught until Tai made his discovery at the dusty airport in California’s High Desert.

Virgin Galactic Spins Its Way Back to Rubber Engine for SpaceShipTwo

Despite Richard Branson’s increasingly dire pronouncements (The Time for Climate Action is Now) about how rising global temperatures and sea levels threaten the planet (and his private island home), it looks as if Virgin Galactic will go back to using a carbon spewing rubber hybrid rocket engine to power SpaceShipTwo.

That’s the word from Virgin Galactic officials in Mojave, who say that the rubber/nitrous oxide engine they previously abandoned is now performing better than the supposedly superior nylon/nitrous oxide engine they abandoned it for in May 2014. It’s not entirely certain, but it looks that way.

Flashback: Virgin Galactic Announces Switch From Rubber to Nylon Engine

Parabolic Arc Flashback: One year ago, Virgin Galactic announced it changing SpaceShipTwo’s propulsion system from a rubber hybrid to a nylon hybrid engine due to demonstrated better performance. The news was announced on a Friday at the start of long holiday weekends in the U.S. and Britain, a perfect time to dump news when neither reporters nor the public are paying much attention. Sierra Nevada, by the way, was blindsided that their rubber engine was being dropped and their lucrative agreement was going away.

Today, the nylon engine decision is being re-evaluated due to performance. The company recently revealed it is testing both hybid engines again, and it might go back to using the rubber one. That means the company still doesn’t know how its going to power its spacecraft despite being nearly 11 years into the SpaceShipTwo program. That explains why it is taking as long as it is.

MOJAVE, Calif., May 23, 2014 (Virgin Galactic PR) – Virgin Galactic, the world’s first commercial spaceline which is owned by Sir Richard Branson’s Virgin Group and Abu Dhabi’s aabar Investments PJS, has selected a polyamide-based fuel grain to power its hybrid rocket motor for the remainder of the test flight program and start of commercial operations. This decision follows numerous ground test firings and is supported by data collected over an extensive development program.

Space Conferences, Engine Claims and Silly Putty

Over the years, I’ve heard many speakers at various space conferences and events say all sorts of things that I felt…oh, comment on dit?…stretched the truth like Silly Putty. Yes, that’s a polite way to put it.

After a while, I’ve become quite numb to it all — the hype, promises, publicity stunts, optimistic schedules that get blown away like fallen leaves on a windy Mojave day. By this point, most of it just passes over me without meriting so much as a mention.

But, sometimes I hear something that stretches the rhetorical Silly Putty beyond the breaking point. I had just such an experience three weeks ago at the Space Tech Expo in Long Beach, Calif.
