Bristol Blenheim (Mk IV shown) was a British light bomber aircraft 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 was named the Bolingbroke.
The other half of Bismarck's fate (see HMS King George V photo nearby): HMS Rodney's three triple 16in gun turrets, all carried forward of the bridge. Rodney and her sister Nelson were the only 16 in ships to serve in the Royal Navy.
Fred C. Baker looks out of B-17E #41-2432, The Last Straw, which was in the 63rd and 64th Bomb Squadrons of the 43rd Bomb Group during the early part of WWII. It was transferred to the 69th Troop Carrier Squadron in October 1943 when the 43rd completed its transition from B-17s to B-24s.
B-17 Ball Turret Gunner. My great uncle was a belly gunner in one of these. It was before they were retractable. So every landing and even take off was stressful. You would be one of the first things scraped off in a crash.
