SeenItAll,
departing Houston Tx in 2010 my ANR earphones and a Nintendo DS3 "disappeared" from my carry on as it passed thru the security scanner, not noticed until we were airborne and went to get them out of the case. Mentioned it to cabin crew who were not at all surprised, "oh thats Houston for you". Now I don't remove my case from the belt until I've checked the contents, have to sometimes resist the "come on shift yr case" calls.
