STEVE INSKEEP, HOST:
Good morning. I'm Steve Inskeep with best wishes to Felix Baumgartner. He plans to ride a balloon to an altitude of 23 miles over New Mexico and then he will step out into the void. Fearless Felix will be wearing a pressurized suit like an astronaut and expects to break the sound barrier as he falls. He's being advised by a former NASA flight surgeon who lost his wife in a shuttle crash and who wants to improve astronauts' odds of surviving a future disaster. It's MORNING EDITION.
