A lined paper airplane flies the farthest. It flies the farthest because it weighs less than any other type of paper. For example, it weighs less than an airplane made of construction paper and it weighs less than an airplane made of copy paper.
Yes, it can. Weight, number of folds, and wingspan are all factors in making a paper airplane fly farther. A long-distance paper airplane (glider) should have large wings, a small fuselage, and evenly distributed (but also light) weight. It should be held and thrown from the center of gravity.
Igor Sikorsky was the first person to fly in an airplane, in his 1913 airplane called "The Grand." The Wrights were the first people to fly an airplane, but you fly ON a Wright Flyer--it's very open. Sikorsky invented the enclosed cockpit.
