Bixler In Flight Wing Separation

The failure analysis by Prof. Iadevaia on how the wings separated from the fuselage resulting in the crash of Bixler during its 9th flight indicates that the spar did not fail in flight. The embaressing conclusion is that the rubber band that keeps the two wings sections attached was not replaced proir to flight. Here is a good teachable moment in the importance of a pre-flight check list. Watch the thought process that ultimately reveals the cause.
