You can't fly without supply.
I remember the flight safety campaign which drew te link between a pilot not getting his breakfast and a claim not being paid (or somesuch) and the clear link being established that the resultant accident was, in part, attributable to every link in the chain.
I'm RAF, I'm not aircrew or in an aircraft associated trade but if my job isn't to contribute to air power then what the fcuk have I been diong for the last 30 odd years!!
