What happened to the memory of 9/11? ???
On boarding at Manchester last time I went to Singapore I got through with nail clippers with a small knife no problem, and on the SIA flight we had metal knives & forks, and razor blades for shaving!! :P
I also never even got frisked on the way back, or put through the metal detector as I was in a wheelchair, out of laziness ;D, but I could have been carrying anything.
Bring an extra cigarette into the UK and they'll have you :o
