The de Havilland DH.88 Comet was a twin-engined British aircraft that won the 1934 MacRobertson Air Race, a challenge for which it was specifically designed. It set many aviation records during the race and afterwards as a pioneer mail plane. The only flying example is based at the Shuttleworth Collection, Old Warden.
You can find recordings of that aircraft here. It is very rare for the aircraft to fly although the aircraft is sometimes taxied at summer airshow events.

The aircraft is not currently flown but they do a fast taxi along the airfield prior to some displays.
