Usually this happens on flights TO the US, not from. It is sad when a person will risk almost certain death to get out of a place.

I actually got to go to Haiti a couple days ago. The airport was decently secure and we didn't have any issues w/ stowaways. We took extra catering and water down and I got to go around and hand it out, which was really neat. I was really hoping to get one of these trips, but I was just working, if I wasn't working somebody else would have been and done the same thing. Very neat experience though.

We were concerned about any potential stowaway issues, but luckily didn't happen.
