There have been plenty of experiments with flight though. Hot air balloons and derigibles already existed and had for some time. Many many glider experiments, and some truly inventive things which were just considered toys. These being Chinese Kites, and a toy that resembled a helicopter. Basically being a spinning top with an airfoil, it would fly in the air for a few moments. In fact, the Wright Brothers even did some experiments with them, and one is even pictured with Jesus!
However, being a US citizen, nobody can ever change my mind that the Wright Brothers flew first.
