Frank Whittle, an English inventor and RAF officer, developed the concept of the jet engine in 1928, and Hans von Ohain in Germany developed the concept independently in the early 1930s. He wrote in February 1936 to Ernst Heinkel, who led the construction of the world's first turbojet aircraft and jet plane Heinkel He 178.
The first airplane was invented in 1903 by Orville and Wilbur Wright. Their historical flight at Kitty Hawk, N.C., was the first time a machine with a human passenger flew under its own power. The plane rose 10 feet in the air, flew 120 feet and landed after 12 seconds.
