Tale we where told was that when an aircraft crashed on a RAF airfield and they needed to move the wreckage in double quick time a form 26 had to be filled in and then 'Everone' could be legally ordered to drop everything and help clear the wreckage.
Myths and Ledgends I suppose.
Old RUM/BUM/BACCY Navy expression. Numbers 2 and 6 on the guns were the blurks who pulled the weapon back into the firing position, hence "two, six, heave!".
Good to shout when John Reid is heaved off Big Ben perhaps. Git.
