The B.E.9.
The B.E.9 was first created during the Great War by the British Royal Flying Corps. This plane had a large range of fire for a machine gun, which made it stand out amongst its competitors, but this design actually didn’t work out because it left the gunner in a very unsafe position, and the placement of the propellors was so dangerous that it could have cut the pilot in half. A Royal Air Force commander once said that the plane was “an extremely dangerous machine from the passenger’s point of view.”
The Fairey Albacore
There is obviously something very off about a plane if a pilot prefers to fly the older version of it rather than one that is supposed to be new and updated. The Albacore was intended to replace the Swordfish and was designed between 1939 and 1943 for use by the British Royal Navy Fleet Air Arm. Unfortunately, pilots dreaded flying this plane, so it got retired very quickly.
