A bit off-thread I know, but since the subject of sqn badges has cropped up;
I'm led to believe that 230 Sqn's badge comes from the label on Tiger Beer. Apparently, the sqn was assembled in a bar in Singapore, trying to come up with a design for the badge, when someone looked at the bottle in his hand, and viola, a badge was born.
Also, I'm told that 22 Sqn's badge features the symbol for Pi due to the fact that during WW1, 22 Sqn's airfield was next door to that of 7 Sqn, therefore when 22 took off, they flew over 7; 22 over 7 = Pi.
Any other stories?
