TOKYO, Aug. 4 -- The second of two young boys who hid in the wheelwell of an Air Force plane flying from Mongolia to Japan has died, a U.S. military spokesman said Sunday. 'The child, who was between 8 and 10, was suffering from frostbite, hypothermia and hypoxia -- basically oxygen starvation,' said Kevin Krejcavek, spokesman for the U.S. Forces in Japan.
The other boy, who was around 12 years old, was declared dead soon after he and his friend were discovered during a post-flight inspection Friday evening at Kadena Air Base in Okinawa. The boys apparently sneaked into a wheelwell of a U.S. Air Force plane that was delivering blankets and clothing to Mongolia, and died from the extreme cold and lack of oxygen on the flight back to Japan, the spokesman said. Ulan Bator is a commercial airport responsible for its own security, but a U.S. team is there investigating the incident, the spokesman said. The airplane was flown as high a 11,000 meters (37,000 feet) for five hours of flight, the spokesman said.
