their day back. Now, next to the incredible story of the run away. The young man who is oddcy seems impanel to be true. Hiding in the dangerous compartment where they store the wheels for more than five hours. Is it true in how did he survive? ABC's David Kerley walks us through the latest. Reporter: This teenage boy, stowing away in this wide body jet's unpressurized wheel well, flying halfway across the pacific, five and a half hours from San Jose, California to Hawaii and surviving. An hour after landing he emerged from the jet dazed, shocking ground crews. He was weak and fell to the ground and regained some strength and stood up. Reporter: The boy had a fight with his parents. He ran away to the San Jose airport where he was able to scale the fence, and raising concerning about all airports. Under cover of darkness and remains undetected as he proceeded on to the aircraft ramp and proceeded into the wheel well of the aircraft. In a plane this large, there is some room in the wheel well so someone can climb up into that space. Three out of four people who tried this die. They're crushed, fall out or die from the elements. Among the 105 who did try, there are 25 survivors. And tonight, possibly 26. Why is this so hard to believe? Because as the plane gains altitude the air gets thin and temperatures drop dramatically. At 38,000 feet it's at least 50 degree below zero. How was he able to do it? As the jet climbs, he loses consciousness and the nervous system is preserved. In a sense, a Hieber nation. I'm boggled that somebody could hibernating like that. Reporter: The teenager doesn't remember the flight. Hawaiian airlines say the boy is lucky to be alive. The teen is in the custody of child services in Hawaii. His parents have been notified and likely this teenager will be back in the inside of a plane on his way back to California soon. David Kerley reporting.
