whilst in security at LHR (heathrow) i was puzzled as to why my mothers lip-balm was confiscated at in security, as you could imagine, she wasn't happy about it and had to make a comment about having a Surface To Air missile in the lip-balm, which almost lost us our flight! Anyway, could someone tell me why LHR security would think lip-balm could possibly be a threat to an aircfaft ?
