Today when a man steps onto the moon, or something new and important happens, the world learns about it immediately. What did the newspapers say about that first flight in 1903? Strangely enough, they said hardly anything about it at all. There were only a few reports about it in the papers. These reports said very little. Some of the things they said were not even correct. In 1904 the Rights built a second machine. They called it “Flyer No. Two”. They invited some reporters to a field near Dayton to watch them fly. Unfortunately there was some mechanical trouble with the plane and it did not fly at all that day. The newspapermen went away. They were disappointed and did not come back. The Rights went on with their work. In 1905 they built an even better machine, “Flyer No. Three”. They were able to stay up in the air for half an hour and more in this machine. They were ale to turn and climb in the air. Farmers, travelers on the roads around Dayton often saw them flying. But when these people told newspapermen about it, they refused to believe them.

The Rights offered “Flyer No.Three” to the United States Government. The Government was not interested. They seemed to think the Rights wanted money in order to build an airplane. They did not understand the Rights had already done this, and flown it as well. Experts were still saying that mechanical flight was impossible. At the end of 1905, the two brothers took their plane to pieces. The parts were put into a huge wooden case. It seemed nobody was interested.
