Handjob on a plane?

Has anyone ever received (guy) or given (girl) a handjob during a flight? Under a blanket?

How did it happen? Did you know the person? Did you almost get caught? Was it a real messy cleanup? Did you hookup after your flight landed?

This is super high on my fantasy list - especially if it's a stranger but I always seem to get seated next to big fat guys on my flights.

Let me know! I really want to figure out how to make this happen!
