Balloon Launch Glider

Balloon Launch Glider (BLG) was a B division event in the years of 2007 and 2008.

Overview
Balloon Launch Glider's included some similar parts to Wright Stuff planes. For example, these gliders required a wing, a stabilizer, and a rudder (vertical stabilizer). All of these would rest on a fuselage. However, unlike Wright Stuff, there were no motors on BLG's. It is most similar to the event Elastic Launched Glider. They both require building a free flight glider, the difference being the type of launch.

The Competition
Teams needed to bring a large helium balloon to the competition. This balloon would be attached to fishing wire, (or the equivalent) and it would be raised to near the ceiling of a gym. The glider would then be released from the balloon, usually by competitors pulling the balloon out from under the glider. The team whose glider stayed in the air for the longest amount of time was the winner.

Teams were also required to bring a log with a minimum of ten tests to the competition. Each test needed to measure four different variables.
