Rocket Men

There's an interesting piece at The New Yorker on the reasons behind the FAA investigation into Virgin Galactic's big media event flight:
"The rocket motor on Virgin Galactic’s ship is programmed to burn for a minute. On July 11th, it had a few more seconds to go when a red light also appeared on the console: an entry glide-cone warning. This was a big deal. I once sat in on a meeting, in 2015, during which the pilots on the July 11th mission—Dave Mackay, a former Virgin Atlantic pilot and veteran of the U.K.’s Royal Air Force, and Mike Masucci, a retired Air Force pilot—and others discussed procedures for responding to an entry glide-cone warning. C. J. Sturckow, a former marine and nasa astronaut, said that a yellow light should “scare the shit out of you,” because “when it turns red it’s gonna be too late”; Masucci was less concerned about the yellow light but said, “Red should scare the crap out of you.” Based on pilot procedures, Mackay and Masucci had basically two options: implement immediate corrective action, or abort the rocket motor. According to multiple sources in the company, the safest way to respond to the warning would have been to abort. (A Virgin Galactic spokesperson disputed this contention.)

Aborting at that moment, however, would have dashed Branson’s hopes of beating his rival Bezos, whose flight was scheduled for later in the month, into space. Mackay and Masucci did not abort.
"
I love flying, but unpowered aircraft, gliders and hot air balloons, have always given me the creeping willies. Not having your own source of power aboard really limits how much input you have on where you come down, it seems.
