I agree with MaxReheat. What I worry about more is that with such over-reaction these days, some poor soul is going to be inbound doing a diversion when they close an airport and they won't be able to make it to another runway with the minimal fuel their bosses legally restrained them from carrying. I wonder what the police and the airlines will say about their overabundance of caution and meeting of legal minimums being proper if they find yet another non-bomb and have to admit that it was completely their fault that an airliner was lost with hundreds of fatalities?
Whilst it may have been an over reaction this is just plain twaddle.
