The Bristol Blenheim holds an important place in aviation heritage as Britain's first all-metal monoplane and the fastest bomber at the outbreak of the Second World War. Centrepiece of this manual is Blenheim Duxford Ltd's Blenheim Mk I, G-BPIV, restored to flight by the Aircraft Restoration Company at Duxford. The author has been given exclusive access to all stages of the rebuild, which he has photographed in detail to give the Blenheim the authentic 'Haynes Manual treatment'. Also included is an interview with pilot John Romain on flying the Blenheim and a review of Blenheim/Bolingbroke owners in 2015.
