The patents and courts do not say they invented the airplane, once again for the third time "new and useful improvements" was the patent, which was all about the means of control. A list of all their patents,
1. Flying Machine, Construction and Design of 1902 Glider (the "new and useful improvements"), Patent No. 821,393
2. Flying Machine, Automatic Stabilizer, Patent No. 1,075,533
3. Flying Machine, Yaw Control, Patent No. 987,662
4. Flying Machine, Vertical Rudders, Patent No. 1,122,348
5. Mechanism for Flexing the Rudder of a Flying Machine, Horizontal Rudder, Patent No. 908,929
6. Airplane, Split Flap, Patent No. 1.504,663
7. Toy, Type of toy in which and object was projected through the air and caused to be engaged and supported by a swinging bar, Patent No. 1,523,989
Everyone, including the Smithsonian, has jumped on the "they invented the airplane", and they can shout it from the roof tops for all it matters, because it's not the case, and the Brothers never claimed it to be the case. Just a little nationalism coming to the fore on their part.
