I think they used to use the York, which later formed part of a little museum by the Dan-Air hangars. There was a Dak - don't know what happened to that; the York and the Ambassador, both of which were donated to Dxford and are now restored.
Think the Scouts later used a Comet which was parked on the gliding side of the field, west of the hangars. Seem to recall seeing one parked there... long time ago, memory now enfeebled!
