One time at my university the engineering department had this paper airplane competition, everyone was given a sheet of 8.5x11" paper and a paper clip. It was particularly windy that day and the event had been organized for better weather so we ended up having to throw the planes directly into the wind from ground level. The distance of the various planes people built ranged from -10 feet to 20 feet from launch point. Taking this into account I decided to modify my design at the last second. I stepped up to the launch area with my plane, aimed it at a 45 degree angle, crumbled it up into a ball and threw it as hard as I could. I got something like 40 feet and had the furthest distance. I kept saying that it was designed to minimize air resistance but In the end I was disqualified for being a smart ass.
