Thought of that
Blue up
I thought of that during an extremely long delay in Manchester shortly after the latest foiled attempt. I happened to mention to the chap in the extremely long queue behind me that if the terrorists had any sense they would put the bomb at the security desk as they wouldn't have to go through security and on that day the impact would certainly have been more devastating numerically wise than your average flight. He seemed somewhat alarmed but that may have had something to do with my N I accent.
