The Smithsonian didn't want the original Wright Flyer back in 1910 when it was offered due to the Langley bias. Charles Walcott was dead set that Langley's old Aerodrome should have been the first successful powered airplane. The Smithsonian finally accepted it in 1948 and it is as original as it gets.

Otto Lilianthol had his trial and error information but Wilbur and Orville knew that it had to be expanded so they did their own experiments. The little wind tunnel did the trick. If you look at the big wind tunnel at Langley Research Center then you know how far it has come since then.
