Try making an appointment with the head of airport security, and explain to him as exactly as possible what you are designing, and ask him (as politely as possible) if you could occasionally come by and run your prototype through their X-ray machine to do a test run or three. Offer to give advance notice to him and/or his people - at least an hour or so. If this will be a commercial product, give credit to the airport for assistance in design testing. Also, send written thanks (preferably on letterhead from the company that this will be marketed by) to the security department, with a copy to the airport manager. Good PR is always good for an airport. I've been pleasantly surprised in the past by what could sometimes be accomplished by just asking nicely. Often the hardest part was screwing up the nerve to ask. -- Mike Werner KA8YSD | "Where do you want to go today?" | "As far from Redmond as possible!"
