kwilson makes a VERY valid point. One thing you'd HAVE to be aware of, though, is the security measures the airports MUST take in today's society. It "may" be a very good potential possibility, though. I'd love to talk to you about it.....because I know some guys, here, ho've gained access to our local airport. If approached the right way....it could be a "win-win" for you and the airport.....but it's probably going to take some legal behind the scenes paperwork. Shoot me a PM or call me if you still have my number. It's worth approaching them....and I may have some of the up-front things you'd need to go in with a plan.
