LWF L Butterfly
The Genesis of the LWF L Butterfly
Following the conclusion of World War I, the “LWF Engineering Corporation Inc.” embarked on constructing a unique light aircraft. This project materialized as the Model L Butterfly, an airplane that, unfortunately, remained a solitary prototype.
Maiden Flight and Lofty Claims
The LWF L Butterfly made its inaugural flight in early 1920. Its designers boldly promoted it with an ambitious claim, presenting it as “the smallest practical airplane in the world,” a title reflecting both their aspirations and the aircraft’s compact design.
A Tragic Conclusion
The Butterfly’s story took a tragic turn on March 31. During one of its crucial test flights, the aircraft suffered a catastrophic failure. This regrettable accident resulted in the death of its pilot, Jack Foote, marking the definitive end of the Model L Butterfly’s development.
