MAKE FOAM AT GRID REF A6
In my early days, we used to have a "booking list" in the tower, which the SMC used during morning fire test callouts. Senior officers and OIC Sports would call the TWRSPR and book foam.
The "foam" was "blood and bone", well before the carcongenic AFFF or "light water".
"Proceed to grid reference A6 and make foam", is one I remember. A6 was the 18th green. From memory Q11 was the rose garden behind the main parade ground flag pole.
Ah, the memories.....
