Answer :
The Wright Flyer was a heavier-than-air plane that was developed by the Wright Brothers, and it was the first powered flight to take place on December 17, 1903. On the other hand, the June Bug, which was built by Glenn Curtiss, flew on July 4, 1908.
Design features of the Wright Flyer and June Bug, which can be found on modern aircraft are Internal combustion engines. However, there is one feature that was found in the Wright Flyer and is no longer found in modern aircraft which is the Wing warping. The Wright Brothers used the wing warping mechanism to control the roll and pitch of their aircraft.
Wing warping is a flight control mechanism that was used to bend the wings and caused the aircraft to turn and bank. Modern aircraft use ailerons to achieve this effect and replace the wing warping system.On the other hand, the June Bug offered the world's first practical and successful aileron, which is a device that provides lateral control over the aircraft. Ailerons are small wing-like structures that are located on the trailing edge of the wing. They move in the opposite direction of each other to provide a twisting effect that allows the aircraft to bank and roll in the desired direction. The ailerons were easier to control and more efficient than the Wright Flyer's wing-warping mechanism.
