The man who fell to earth | UK news | The Guardian As someone has already stated, there was a case around the same time, where someone survived a long haul flight in the undercarriage. They survived it because they lightly dressed and quite skinny (from memory), they very quickly went into a deep sleep/light coma type of stasis, which is what saved him. Apparently, if he'd been better fed and/or wearing more clothing he would have died.
