You are about to see what it's like from the passenger's perspective when catastrophe strikes and a jetliner crashes. This is an ambitious and dangerous test. A boeing 727 was intentionally crashed in the desert to learn what really happens to passengers when a plane goes down and how they can survive it. It's part of the disry channel's plane crash and neal karlinsky has the story. Reporter: Watching the most dramatic moments of a one-way trip ever recorded. This boeing 727 is being deliberately crashed into the desert. On board more than $500,000 worth of crash test dummies, 38 specialized cameras sensors and a crew of incredibly daring pilots wearing parachutes.
