Many wheel-well stowaways are found, dead or alive, with their bodies covered in frost, suggesting severe hypothermia during flight.

How often do stowaways survive?

US Federal Aviation Authority records suggest that, at best, one in four stowaways survives. Others die or fall in transit; some are crushed when the mechanised landing gear retracts into the wheel well; most survivors suffer severe hypothermia or frostbite, often losing limbs.

Has anyone survived being a stowaway?
