I diverted to Newcastle in a Chinook while on exercise. We were all tooled up with SA80 and pistols. We went into the terminal to speak to the handling agent, our gats carefully concealed to avoid alarming the public. All went well until we wanted to return to the cab. The security guy insisted that that we put all our bags and anything metallic through the scanner. His face was a picture as we piled our little arsenal onto his conveyor belt!
