Blenheim Squadrons of World War Two, Jon Lake. This book looks at the entire RAF service career of the Bristol Blenheim, from its debut as a promising fast bomber, through the deadly disillusionment of the blitzkrieg, on to its work in the Middle East and Mediterranean, where the aircraft found a new lease of life. Lake also looks at the use of the Blenheim as an interim fighter aircraft and its use by Coastal Command.
