the person who invented the airplane stall warning is Leonard Michael Greene.
In the mid-1940s, Greene developed the first practical way to warn the pilot of the aerodynamic stall. His first design and apparatus included threaded bolts, a bicycle horn and other odd components, all powered by flashlight batteries. Greene filed his device for a patent in 1944, and the patent was issued in 1949. In order to develop his design, Greene founded the Safe Flight Instrument Corporation in White Plains, NY, in 1946. There, he refined and marketed the stall warning indicator.

NO, the airplane was not invented in Africa.
The first airplane was invented in 1903

When an airplane stalls, the wings lose lift for a brief period. This makes the airplane pitch down sharply to regain airspeed and resume flying.
The Wright Brothers invented the airplane.
The Wright brothers invented the airplane during the Industrial Revolution.
The airplane was invented in the late 1890's. The first recognised flight was in 1903.
The Wright Brothers Invented it in 1901
The flaps on an airplane are there for two reasons: Drag and lift. As an airplane lines up with the runway and descends, it must slow down. Several things are done to slow down, such as throttle the engines down and lower the gear. However is some airplanes, to slow down and remain slow they must extend the flaps. These cause extra drag, which slows the airplane down. They are usually extended in increments while on approach. The second reason is for lift. As an airplane get slower, the wings get less and less effective, and once it gets slow enough, it may stall. To prevent a stall, airplanes lower flaps. These redirect air downward, pushing the airplane up. This allows it to fly slower, past its "clean" stall speed. (Clean stall speed refers to an airplane's stall speed with no flaps or landing gear extended) Some airplanes can fly nearly 100 knots slower with full flaps. The stall speed with full flaps and landing gear extended is known as "dirty" or "landing configuration" stall speed. This is much slower than "clean" stall speed.
Orville and Wilbur Wright invented the airplane.
