In this final lesson, students will demonstrate their gliders during a flight completion. This flight competition can be conducted outside on a calm day, or in a gymnasium, or in a multipurpose room; any place with a clear open space. A 100' tape measure will be placed on the ground and used to measure flight distance, and deviation from the flight path. The tape measure itself will be the flight path. For every foot the plane deviates from the flight path, one foot will be subtracted from the overall flight distance. This will be the "Overall Flight Distance" Each glider will have three flights. Students can change the flight control components they have built into their glider to improve results during the competition. The glider with the greatest Overall Flight Distance will be declared the winner of the competition.
