"We assumed he was at a friend's house. We had no idea where he was". Says the father of a 9 year-old boy who wasn't at a friend's house. By the time his parents figured out he was missing, the boy had somehow snuck onboard an aircraft and travelled halfway across the US as a stowaway.

Without a ticket. And without clearing security.

Flying from Minneapolis to Las Vegas, once found the boy - who has "behavioural issues" - told police he thought he was playing Grand Theft Auto. You know. The mission where you sneak onboard a plane and just sit there quietly.

9-year-old stowaway thought he was playing video game [MSN, thanks R R!]
