A runaway teenager spent a five-hour flight hidden in the wheel well of a plane flying from California to Hawaii, surviving freezing temperatures of -62C.
The 16-year-old boy, who has not been named, is thought to have passed out almost immediately as the plane took off, soaring to 38,000 feet, but regained consciousness at the Kahului airport in Maui, Hawaii.
He jumped out of the plane, and proceeded to wander around the tarmac where he was found by officials.
As the plane soars at 18,000 feet, the oxygen supply becomes so scarce that the boy would have lost consciousness.
Above 33,000 feet, a person would normally need artificial help to expand and contract, and to survive the extremely low temperatures.
