On the way back from my last trip to India, everything got scanned at Heathrow.
They must have thought I looked suspicious as I then got my bag swabbed and checked for bomb residue with a GC-mass spectrometer. Iím a retired research chemist so found it quite interesting. Of course they found nothing, but wonder if all the cassettes of exposed film loose in a zip lock bag looked unusual to them?
Iíve always been taking film out of the box to make inspection easier, not sure this helps.
