Air-flight drastically changed when the Wright brothers created the first Airplane. It had to chain driven motors mounted on wings. Funny fact: The parachute was made before the plane.
here's a Timeline:
1903: First sustained flight with a powered, controlled airplane.
1914: Automatic gyrostabilizer leads to first automatic pilot.
1914-1918: Dramatic improvements in structures and control and propulsion systems.
1917: First all-metal plane.
1925-1926: First air-cooled engine.
1933: First Passenger plane.
1935: First Practical Radar.
1937: Jet-Engine designed.
1939: First practical singlerotor helicopters.
1939-1945: World War II spurs innovation.
1947: Sound Barrier Broken. Speed of sound is approx. 650 mph.
1949: Commercial aircraft.
1950's: B-52 bomber is made by Boeing.
1969: Boeing 747 is made, nobody thought it would fly.
1990's: B-2 bomber developed.
1995: First aircraft produced through computer-aided design and engineering.
1996-1998: Joint research program to develop supersonic airliner.
