The Coanda-1910 was the first jet-propelled aircraft ever built. It was constructed by Romanian inventor Henri Coanda. The aircraft was quite unconventional in design, and its most striking feature was its powerplant, since it featured a kind of thermojet, a hybrid of jet engines and piston engine technology.
The inventor Coanda was unaware of how powerful the engine was and during a test flight went airborne and crashed. WI instead of stopping his developements he kept trying to get his airvraft to fly? Would jets come about sooner? Would they see any action in WWI?
