Which individual is credited with inventing the jet engine?

The invention of the jet engine is attributed to both Sir Frank Whittle and Hans Von Ohain, making the answer to this question correct. Sir Frank Whittle, a British engineer, is widely recognized for developing the turbojet engine, which was a significant breakthrough in aircraft propulsion. His first engine ran in 1937, and he successfully demonstrated it in flight in 1941. Concurrently, Hans Von Ohain, a German engineer, independently developed a jet engine that powered the Heinkel He 178, the world's first jet aircraft, in 1939.

By acknowledging both Whittle and Von Ohain, the correct response highlights the simultaneous advancements made in different parts of the world that contributed to the evolution of jet propulsion technology. Meanwhile, the other options include individuals who made valuable contributions in their respective fields, such as rocketry and electrical engineering, but they are not directly related to the development of the jet engine.
