The Bristol Blenheim was a British light bomber aircraft designed and built by the Bristol Aeroplane Company that was used extensively in the early days of the Second World War. It was adapted as an interim long-range and night fighter, pending the availability of the Beaufighter. It was one of the first British aircraft to have all-metal stressed-skin construction, to utilise retractable landing gear, flaps, powered gun turret and variable pitch propellers. A Canadian-built variant named the Bolingbroke was used as an anti-submarine and training aircraft.
Blenheim Mk.IV N3589 of No. 40 Squadron RAF landed in error at Pantelleria on 13 September 1940 and was evaluated at Guidonia airfield near Rome. One more was captured in Yugoslavia while two were seized in Italian East Africa but were recaptured when this territory fell into British hands. N3589 might be the Mk.IV appearing in a non-flying role in the movie Un Pilota Ritorna (1942) directed by Roberto Rossellini.
