When did John Stringfellow fly a model with a tiny steam engine?

John Stringfellow successfully flew a model powered by a small steam engine in June 1848. This event is significant in aviation history as it marked one of the earliest instances of engine-powered flight. Stringfellow's pioneering work demonstrated the feasibility of using steam power for flight, which was a considerable technological achievement at the time. His model, known as 'The Monoplane,' is recognized for its innovative design, which contributed to the development of heavier-than-air flying machines. This flight experiment laid the groundwork for future developments in aviation and sparked interest in powered flight.
