Welcome to Warbird Wednesday! Today, we are looking at the Felixstowe F5L aircraft, particularly focusing on its historical significance during World War I. The F5L was a sea plane with 227 units built, produced by the Naval Aircraft Factory, Curtis Aircraft, and Canadian Sea Planes Limited. Introduced in 1918, it served as a standard patrol aircraft until its retirement in 1928, showcasing the rapid advancements in aviation during that period. The aircraft was a derivative design of Glenn Curtis’s work, designed by John Krill Porte, and played a crucial role in naval operations, especially against capital ships. The technology of sea planes, highlighted by the F5L, evolved but eventually faced a dead end, leading to their discontinuation in military use.
