Seems another poor soul decided to stow away aboard an airliner recently by getting into a wheel well... a flight from South Africa (with a stop in Senegal) lowered its gear over Long Island on approach to JFK and a leg and part of a torso fell into some lady's backyard... other remains were discovered inside the well after the plane arrived. :-/
Hard to say which killed him first- the mechanism , the high altitude, or the subzero temps, but whatever the case, I can't believe people still try this. You'd have to be as stupid as you are desperate to think you'll survive such an adventure. And it happens often enough (newspaper reports 5 such incidents in the last 5 years at NYC area airports) that one has to wonder if anybody bothers with walkarounds anymore in places like Senegal... maybe they figure that mere human flesh and bone won't interfere with the gear mechanism, but this would actually be a pretty good way to plant a bomb, if one could get that close just before takeoff.
