When I was in first grade I was told it was the Wright brothers who invented the airplane and I still find their names on the first page of Google. But I have heard of an Indian who invented the airplane eight years before Wright brothers first unmanned airplane in 1895. and he was successful flying in the air and landing perfectly on the ground. So I am confused who invented the airplane?
You need to research George Cayley who worked out the principles of modern aircraft in the first decades of the 19th Century, and flew heavier than air gliders by mid century.
But that should not detract from the real achievements of the Wright Brothers in constructing prototypes of practical heavier than air flying machines. Heavier than air flight by the beginning of the 20th Century was in the air (so to speak).
