Hmm..... BALPA advising others on airport security?
Why not let the security managers advise BALPA members on how to fly an aircraft?
BALPA seem to be out for one thing here, making their members' working day a bit easier. Now I'm all fot that, but let's let security experts run the security side of things, and let BALPA worry about flying.
They are experts in their own fields for a good reason. Sure there are problems at the moment, but it will settle down.
