Felix Baumgartner, the Austrian skydiver attempting to break several frreefall records, has lifted off from Roswell, New Mexico and is ascending into the stratosphere and beyond as I write. The helium balloon that's lifting him upward is, right now, nearing 100,000 feet at a rate of about 15 feet/second. He hopes to reach 120,000 and then leave the capsule for about a 10 minute jump back to Earth. Half of that time will be spent in freefall. That's all I know. You can watch a delayed webcast of it at the BBC website.
