It seems that at Bournemouth airport at least, aviation enthusiasts are going to be able to help in "spotting"(excuse the pun) anything suspicious:
To me it seems like a great idea as the same skillset that is used to be a successful spotter (attention to detail etc) would benefit such an undertaking.
What does everybody else think though. Could you spot and fight crime at the same time (i see a comic book hero here)
