Answer:
First electric light bulb, invented by Thomas Alva Edison in 1879 and patented on January 27, 1880.
Frank Whittle, an English inventor and RAF officer, began development of a viable jet engine in 1928, and Hans von Ohain in Germany began work independently in the early 1930s. In August 1939 the turbojet powered Heinkel He 178, the world's first jet aircraft, made its first flight.
