Felix Baumgartner’s 23-mile supersonic skydive attempt aborted due to winds

October 9, 2012

A combination of technical problems and gusty winds caused Feliz Baumgartner’s record-breaking 23-mile supersonic skydive attempt to be aborted just as the balloon was being inflated today. They had a good window of calm winds to work with, but weren’t able to get the balloon off before a gust of wind came along and blew parts of the partially inflated balloon onto the ground. This is a dicey situation, because the balloon material is so delicate and folded so meticulously that once it’s been unfolded, it cannot be deflated and used again. As far as I can gather from what was said during live webcast, they only have one backup balloon. Since this is the largest balloon of its type ever made or used, it’s REALLY expensive, so they really have to get it right on the next attempt.

The air at the surface, and for roughly the first 1,000 feet off the ground, must be absolutely still for the launch to happen safely. Even a little bit of crosswind can take the balloon off course, dragging the capsule across the ground or smashing it into anything nearby, just as NASA learned first-hand a few years ago during this failed balloon launch in Australia.
