The failed attack by the Underwear Bomber on Christmas Day has once again made governments jittery about airport security.

At the same time, the news has thrown up some bizarre stories, such as the security lapses which brought Newark to a standstill recently, and the drunken bravado of three passengers on a plane at Heathrow.

But the strangest of all has to be the one about the Slovakian man who had unwittingly carried explosives onto a plane headed for Dublin as part of a security exercise!!
