Have you ever wondered how big airplanes weighing several tons can stay afloat while gliding across air? Well, that’s what I’m here to inform you about. Airplanes are able to fly because the jet engine or propellers produce a jolt. Some important variables while going at supersonic speed during a flight or a low-speed flight are speed, density, load, angle of attack, and wing area. The wings work by air flowing over and under them. When air does this it makes the plane go up or down. This act is indicated because the air flowing over the wings travels faster than the air maneuvering underneath the wing, the top air has lower pressure than the underneath air producing lift. The fuselage also works very similarly; the fuselage is the big tail wing in the back. Air maneuvers over and under lifting and releasing the plane down. The cockpit is the place where the pilot can control the plane with many buttons and controls.
Draft works like a crumpled piece of paper, if you were to throw it, it would go further than a piece of non-crumpled paper, due to draft. Lift needs to be stronger than weight for the plane to stay afloat the air. Also, thrust needs to be stronger than draft for the plane to move forward and not back. The aircraft controls, control the rudders, ailerons, and elevators. Ailerons are almost like rudders except they are located on wings. They also, are part of the flying machine for a different purpose. Ailerons are on each wing near the rear of it, both are moved at different times in opposition. What this does is, put the plane in the direction to turn or curve. Elevators are located at the rear of the fuselage, what they do are they change the angle of the plane, for instance, if wanted to go down, you would use the elevators to to point the nose downward. The rudders are the wing related objects located on the top of the fuselage, which can move or adjust the way the pilot wants them so that the plane moves through the air. The control panels are very confusing, people have to go through many years of flight school to learn all of what each button or lever do. I would highly recommend not to try and fly a plane if not fully surtified.


On December 17, 1903 the Wright Brothers were the first successful in flying an airplane. Even though they were successful, the flight only lasted about twelve seconds. Many people deterred the Wright Brothers to keep going on with their experiment, but they didn’t listen. The Wright Brothers lived in Kitty Hawk, NC. The first liftoff took place at Kitty Hawk Beach. They had many failed attempts, but they finally succeeded. They are the reason we use flying as one of the most popular transportation machines.
