Shown here is Lancaster B.Mk.III, P4-C, (LM550) of No. 153 Sqd based at Scampton in 1945. While the aircrew looks busy, the outer petrol tanks are filled simultaneously from a 11, 365 l (2,500 Imp gal) AEC bowser, two engine fitters toil on the port inner and a third tops up the port-outer's oil tank from the towed bowser visible behind the aircrew.
