I really can't believe that. These liquid security measures seem so arbitrary and ultimately useless. I flew through Gatwick yesterday, and they just made you put all your liquids (including foundation, mascara, hair gel) into a plastic baggie as you were going through security. What exactly is that supposed to do or prevent?
I also am suprised to read that it happened at BHX. Wasn't there just a report earlier this week about the fact that airport security there was rather lax? If this happened in the last couple of days, however, perhaps they were being overly cautious since there has been some bad press about security there.
