Airport authorities in the US are trying to work out how a 16 year-old boy survived a five hour flight hidden in the wheel well of a jet liner.
During the journey from San Jose airport in California to Maui in Hawaii, the plane climbed to 12,000 metres.
The 16-year-old who was picked up by police after being spotted by ground crew, apparently lost consciousness due to a lack of oxygen and temperatures in the compartment dropping to minus 62 degrees Celsius.
Lucky to be alive, the stowaway arrived in Hawaii with nothing but a hair comb. When questioned he told FBI officials he had run away from home.
