Wright brothers used few tricks, to make success faster, because of very early stages of flight tech. First, they spent few years in meteorological archives, to choose very special place for flights - with constant strong winds and with significant long descent. Only second, they spent time to create best motor, with unprecedented power/mass ratio, and only because automobile manufacturers avoid their order (because thinking, it will not lead to big series). And Wrights was not first to flight, but they was first to make more or less reliable controlled flight. And Wright was first to create rule - two brothers should not fly at one plane at same time, for safety reasons.
