He gave exhibitions also in Germany and Italy and instructed Italian army officers in the flying of Wright machines.

At this time Orville was giving similar demonstrations in America.

Transverse control, the warping device invented by the Wright brothers for the preservation of lateral balance and for artificial inclination in making turns, has been employed in a similar or modified form in most airplanes since constructed.
There was no "mine" or "thine" in the diction of the Wright brothers; only "we" and "ours." They were joint inventors; they shared their fame equally and all their honors and prizes also until the death of Wilbur in 1912.
