Question: which scientist invented the airoplane and do you know how they did it abd what motivated them?

Wright brother (Orville and Wilbur Wright) invented and built the first maned airplane that has successfully flown. Apparently it was a toy “helicoptor” they had when they were younger that sparked their interest in flying.

From what I could gather from the Wiki page (I might have missed stuff.. I’m not too familar with this area and it seems like an interesting and long journey):

They did it by a lot of studying, practicing and experimenting. They believed that gliders are the key to flight, but as some gliders at the time were killed in accidents, they looked into establishing a reliable method of control. They studied designs of previous inventors, looked at how birds fly, did their own experiments on kites/glider flights to challenge the coefficient of air pressure that was traditionally accepted at the time, carried out tests using small homebuilt wind-tunnel (testing different miniature wings/airfoil shapes and propellers), asked their shop mechanic to make a specialised lightweight engine, and trained themselves in a lot of glider flight so they can get a better control of the aircraft. After much testing/improving of their model, eventually their plane took off in 1903.
