Surely the Mk 16 landing on the cricket ground after engine failure was during the first BoB flypast over London, when an awful lot of Fighter Command was involved. The actual cricket stumps it hit were preserved in Bentley Priory OM when I was there in 1969, together with pictures of the pilot (a Wing Commander?), aircraft and associated other memorabilia of the incident and photographs of the sky apparently full of Spitfires, Hurricanes and others (but no Defiants!)
