RAF Stafford had (has?) a Harrier GR3 and whilst it has an HLS for refuelling passing rotary assets it never had an airfield and RAF Locking had a Mossie, a Spit, a Gnat and I believe a Meteor at various times without an actual airfield on the camp, although during WW2 Mossies were built on site then taxied down the road to RNAS Flowerdown for onwards air movement.
