Reading the posts about the AIB and potential candidates being concerned over what they need to know, it reminded me of my Fleet Board in 1980. The most useless facts I remember from that event both stem from a grilling I had at the hands of a member of the White Mafia on the subject of the Naval Catering Manual (BR7?). The useless facts are: 1. It takes 71/2 minutes to boil a cabbage. 2. When a bottle of champaigne is cooled to the correct temperature, the cork is under the same pressure as the back wheel of a London bus, namely 64 pounds per square inch. It forever baffled me that a Seaman Officer would be required to have such knowledge, but there you are. What other useless facts have others learned?
