30 Sqn Centenary
I suspect it wouldn't be correct as per the drill manual, nor is 30 big enough by itself to mount 2 flights which is the minimum needed. On any other squadron (non-Hercules) the people who service the aircraft would be a part of the unit so I don't think it's a gross misuse of the manpower although I'm sure for the individuals concerned there were probably quite a lot of things they'd rather have been doing.
