This is where john macready and oaklet kelly's plane is. This plane is cslled the t2. The t2 is a plane made by the dutch for transport. It was the first plane used for a non stop trans continental flight. Without them, our planes would not go as far and well as they do now./// Ibrahim

Otto Litienthal created a hang glider design that was inventive and successful. It had broad wings that folded easily for storage. It could be controlled by the flyer shifting his weight back and forth, moving the glider's center of gravity. It could go up to 1150 feet in the air. Its maneuverability and the massive lift given by its cotton covered wings were used by the wright brothers as they designed the world's first airplane.

This is where the lilienthal hang glider is. It was invented by Otto Lilienthal in 1894. It worked like this: the wing and tail surfaces are covered with doped cotton cloth and a horizontal stabilizer is connected to the frame by a pivot at the front of the rudder. The wing folded rearwards for storage and transporting, and the pilot went between the 2 wings./// Ibrahim

Otto Lilienthal created the first hang glider in 1894. The machine inspired the Wright brothers to create the first airplane.

Wings on an aircraft give it lift and reduce drag. They create different pressure zones to increase flight capability. Without wings an aircraft couldn't turn or even fly.
-Hunter

this is the wright brothers glider it was the first thing to flight. the historic flight took place in 1903.

Each of the 4 elements combine and help/go against flight. Lift and thrust help the plain fly, by getting it up and flying, while gravity and drag slow ad bring it down. The sharp edge of a wing creates it so air pressure won't follow it like it would with a rounded edge.///Ibrahim

Thrust boosts the aircraft. Drag lets the aircraft slow down and control acceleration. Lift helps the aircraft take off and stay up. Weight of the aircraft lets the aircraft land. All of these give aircrafts flight control-Hunter

The four elements of flight are lift, weight, thrust, and drag. Lift is the force tha acts at a right angle to the direction of. Motion through the air, weight is the force of gravity, thrust is the force that propels a flying machine in the direction of the motion, and drag is the force that works against the motion.///Ibrahim

This is the main library of congress. It is beautiful and gives me happy feelings. I love the architecture.///Ibrahim
