The B.E.9.
During the Great War, the British Royal Flying Corps made the B.E.9., an experimental plane. What made it so different from older models would be the expanded field of fire for the machine gun. Sadly, the feature backfired because it left the gunner in a vulnerable position. The propeller blades might cut the pilot in half and the engine could crush a person in an accident. An RAF defenses commander said it was “an extremely dangerous machine from the passenger’s point of view.”
The Fairey Albacore
Clearly, there is something wrong with the plane if a pilot wants to fly an older model instead of the new one. Fairey Aviation launched the Albacore as a replacement for the Swordfish. Constructed between 1939 and 1943, it was meant to be used by the British Royal Navy Fleet Air Arm. Pilots hated flying the single-engine biplane torpedo bomber so much that it got retired earlier than its predecessor.
