A method and apparatus for recovering fuel vapour from a fuel tank of an aircraft comprising a fuel tank, a wing 3, and an opening in the underside of the wing, where the inlet 13 to the recovery system is coupled to the opening, and the fuel vapour is captured from the fuel tank which flows out of the opening, and outlet 14 conducting the vapour to be collected in a vapour storage tank 11. The inlet may surround the opening and couple without plugging in, and may have one or more suction cups which attach the inlet to the wing. One or more brackets may protrude from the wing’s underside to attach the vapour recovery system inlet. The aircraft may comprise a vent tank and vapour may flow from the fuel tank to the opening via the vent tank. The method or storage tank may comprise a land based vehicle 10 that may also feed liquid fuel into the aircraft and the captured vapour may be transported to a storage tank by the land based vehicle. The vapour may be captured as the liquid fuel is added. Liquid fuel that overspills from the fuel tank may be captured by the recovery system and stored in the vapour storage tank.
