constructed an air tunnel to compare the shapes of a

suitable plane wing.

This was by attaching an old store fan to a 6-foot

wooden box, and they blew air into several miniature

wing models with different but accurate measurements,

and in the end they came up with a number of

successful measurements of the plane's wing, and the

brothers also made countless kites as well as gliders. To

test the various designs of the aircraft, they also

successfully studied and analyzed the movements of

birds.

In the end, the Wright brothers felt that they

were ready to test their plane, but wanted to try it

out in the right place, and wrote a meteorological

request in the United States, and Kitty Hawk told
