Original post is an urban legend.
The one about the guy who "parachutes from the rear stairs of a roaring jet" - that is presumably how a hijacker, named "D.B. Cooper" in the media, escaped after receiving his ransom. Neither he nor the ransom money has ever been recovered. It is a true story.
Here's another urban legend:
State troopers find evidence of a fiery impact on the side of a cliff. They are baffled when they find pieces of scorched metal and two human teeth embedded in the impact zone. They later discover that a man had stolen a jet-assisted takeoff assembly from a local air force base, and determine that the man strapped the JATO to his car. Upon ignition there was no way he could stop his car, but an attempt to brake left scorched rubber on the highway and launched his car into the side of the cliff.
