Question

_______ brothers invented first air vehicle.

Answer 1

Hello friend
-------------------------------------------------------------------------------------------------------
Wright brothers invented first air vehicle.

They made the first controlled, sustained flight of a powered,

heavier-than-air aircraft on December 17, 1903.

In 1904–05 the brothers developed their flying machine into the first practical fixed-wing aircraft.

Although not the first to build and fly experimental aircraft,

the Wright brothers were the first to invent aircraft controls that made fixed-wing powered flight possible.

Hi friend, the wright bro there invented first air vehicle.

It was invented on 17th December, 1903.

Orvillie wright and Wilver wright were the two American brothers who invented the first airplane.
In July, 1899, Wilver wright put wing-wraping to the test by building and flying a biplane kite with a five-foot wingspan.
In the year 1900 both the brothers went to Kitty Hawk in North Carolina , to start their first manned gliding experiments.

After a lot of failure in the experiments finally in the year 1903 on 17th December they invented the first airplane. It was named "wright flyer".
