You're going to be popular with the spotters FEW CLOUDY !! They have to put up with enough kneejerk total nonsense in the name of security as it is. Let's be honest, with the right weapon (and Bin Liner's lot can afford them) they don't need to be anywhere near the airport perimeter. Five miles out will do fine. How do you plan to organise effective security for say a radius of 20 miles around all of the worlds' airports without increasing the price of flying by about 1000%?
In fact, come to think of it, spotters are probably the cheapest and most effective security you can have around an airport. They will soon notice anything suspicious going on. What airport managements need to do is encourage local spotters and give them a special telephone number to call as soon as they observe any suspicious activity. Now that would make a lot more sense to me.
