There is the (in)famous story of a 22 sqdn Whirlwind (or was it a Wessex?) running out of motion lotion whilst heading north back to Boulmer. It landed on the hard shoulder of the A1 and was "towed" (pushed?) into a petrol station where the boss put 100 gals of Esso Pink (Parafin) and a quart of Castrol GTX (oil) into the fuel tank and offered a "Big White Queen will pay the bearer" chit to the bemused gal on the desk. He is alledged to have asked for the green shield stamps too!
