they made 4 planes before they became successful
Well I think 105.
The Wright brothers DID NOT "create the world's first airplane" - they built on the success and failure of others before them and prevailed to have the first successful flight.
The wright brothers built thirty planes by them selves then had other people help build. altogether they built one hundred planes, while the wright brothers were alive.
koala brothers
The Wright Brothers put propellers on all of their planes. There were no jet engines then.
the wright brothers first invented planes
because the Wright Brothers invention taught people how to build planes without their invention we wouldn't have planes
they built planes because it was mans dream at the time
The Wright brothers tested their planes by using gliders to understand the principles of flight and control. They conducted numerous test flights with manned and unmanned gliders to gather data on lift, drag, and stability. Once they were confident in their design, they moved on to powered flights with their first successful airplane in 1903.
One they hade made themselves. They were the first people successfully to demonstrate powered heavier-than-air flight. There were no planes before the Wright brothers.
