Still can't see how you can stop fantatics and zealots getting Sky Marshall jobs. The guys behind Sept 11 seemed pretty competent types, so I guess they'd qualify. And how can you legislate against the occasional sky marshall flipping? I wouldn't expect either of these to happen every day, but I would have thought once every fifty years was pretty often for this sort of thing.

The simple fact is, there is no defence against intelligent, determined fanatics and zealots, especially if they're happy to die in the cause. That said, we're all more likely to be killed by a piece of office furniture than in a plane, hijacked or not. Like Woody Allen said today, let's keep a sense of perspective and get on with our lives. We might get clobbered by a filing cabinet tomorrow anyway, so what the hell.
