Nervous Moments

Popped down to the airport on the way home from work to have a look...Massive security operations started at UK airports today after 20 people were arrested. They are said to have been planning a mass terrorist attack on planes flying from US and UK airports.

I only managed to fire off 100 pics in an hour, before the police moved me on, because I was "parked on a narrow bit of the road"...No questions about what I was doing there or anything.

This is a 'critical' state of alert. I'd like to know what they'll do when it gets really critical? Put their sirens on maybe...
