For awhile, the state was considering offering free one-way tickets back to the mainland for homeless people originally from out of state. That could of really helped the low-budget surf traveler - hop into a wheel well for the trip to HI, get the free homeless return ticket. Might be kind of hard getting a quiver into the wheel well though.
There was a kid a year or so that did the same thing except he fell out on take off. They found his mangle corpse in the woods. and a greasy hand print in the wheel well. Seems pretty easy to get on the tarmac. The real threat is if some malcontent throws something in the hole. Maybe, instead of fondling old women and children, the TSA might want to secure the perimeter a little better.
