Back in the 1970s there was a flight safety poster around which purported to show all those everyday items that were deemed to be dangerous and therefore forbidden to be carried as a pax on Her Majesty's aircraft. This poster was primarily aimed at brown jobs whose luggage apparently routinely contains matches, cigarette lighters, hexamine blocks, methylated spirit, hand grenades etc, etc.
The wonderful RAF movers had, in their wisdom, decided that aerosol deodorants should be placed on this dangerous items list. (Quite why I have never worked out as in over 30 years of flying as a pax not once has an aerosol deodorant exploded in my luggage).
The poster had a photograph of all these dangerous items, but with "sanitised" brand names. It has always amused me that the aerosol deodorant sported the name "Pong-Go".
