That's an effect of the increase and decrease in pressure which goes along with the altitude change.
I think he built the first flight airplane.
Yes. They were the first people to build and fly an airplane. Their first flight was in Kitty Hawk.
Because of the pressure build up in your ears.
The Wright brothers finished building their first airplane in 1903. On December 17, 1903, the first airplane flight took place.
A single person can build an airplane.
he build a airplane for eaiser transportation! he build a airplane for eaiser transportation!
no
The first successful flight of a self-powered airplane was December 14, 1903. But they flew unmanned gliders as early as 1902. The Wright Bos built airplanes until 1912 (Wilbur died in a plane crash), but the Wright Bros. airplane company built airplanes for decades.
Companies that build airplanes
Knowledge is power
The airplane was lifted to the surface of the lake due to the accumulation of gas inside it, caused by its engine running which led to internal pressure build-up and eventual release when the plane broke the surface tension.
So they can travel.
