I still think your sleeper scenario is wholly fantastic Bernoulli. I'll credit you with intelligence and assume you're not suggesting the scenario of a sleeper flying his aircraft into a building but the idea of a UK licenced pilot supplying explosive hair gel to terrorists? It's a bit far fetched. There are much easier ways to get a tube of toothpaste into the secure zone than to train a sleeper to fly, get him a job and then wait for a toothpaste plot to evolve. AQ are patient but they're not stupid, and bang for buck, thats got to be a pretty cr*ppy idea. If you still think the sleeper is a possibility then lets have positive vetting and iris scanning for all UK licenced flight crew then we can work with security instead of against it.
What is most tragic about this latest security farce is that it seems to have finally tipped the balance amongst pilots. For years we've complied with increasingly stringent (and pointless) security restrictions in order to be seen to be playing the game. Now we are actively working to get around the restrictions, looking for loopholes and workarounds to avoid the restrictions which have been imposed ostensibly to protect us. The lunatics really have taken over the asylum now.
