I've looked at some old OS maps of the area and can't see any airfield marked - however on a map that was made of bench marks(!!), when they were laying out the ring road, there appears to have been a linear airstrip type feature just west of the Black Dam Roundabout, just south of the London Road on the edge of the Common oriented SW-NE - this is pretty much the site of the Crowne Plaza Hotel now - accessed by Old Common Road
