The secnd was hw t cntrl it nce it was flying. Fr bth prblems, they fund their slutin by lking at hw birds flew. After they slved these prblems, they added an engine t the glider. Then, in December 1903, the wrld's first plane flights were made.
Para 3: EffectThe inventin f the plane has made ur travels arund the wrld much easier and faster. Jurneys that nce tk days, weeks, r even mnths, can nw be made in nly a few hurs. As a result, cmmunicatin amng peple in different cuntries is nw much easier, and the wrld has becme a much smaller place.
