Nice one Asturias56. My best was a backpack that I used for work in my days in telecomms. I decided to use it for a long weekend around 2006. At LTN, I was pulled smartly and asked if there was anything dangerous in it?
The X-ray found a pair of small wire side-cutters that had got between the lining and I thought were lost. They were not happy that I was so pleased and thanked them for finding them! They wanted to confiscate but I went back out, bought a padded envelope and posted them home. Good side-cutters are expensive.
