Clearly, the teen who decided to run away on Sunday to Maui via the wheel well of a Boeing 767 is lucky to be alive. Some wonder how it's even possible.
First, he had to get around security at San Jose International Airport. Surveillance camera video shows him hopping the fence at the airport in San Jose, Calif., and walking across the ramp toward the Hawaiian Airlines plane, according to airport officials. But then, the story gets even more incredible: The boy says he got into the wheel well of the airplane, and crawled out again once the aircraft landed in Maui.
What Happens If You Get Sucked Out of a Plane?
"For somebody to survive multiple hours with that lack of oxygen and that cold is just miraculous," airline analyst Peter Forman told CNN affiliate KHON.
But not completely unprecedented. Between 1947 and 1993, five people survived flights in wheel wells at heights up to 39,000 feet, and five did not, according to a study by the Federal Aviation Administration.
"As you go through 10,000 feet, you develop something called hypoxia, which is a starvation of oxygen," Michael Kay, a retired British military lieutenant colonel, told CNN. "So on a gradual ascent ... a person will slowly slip into a state of unconsciousness. Because of the altitude, you're at around -80 degrees. It is freezing, but that has its benefits: it preserves the central nervous system."
