Multi-Winged Planes Are Aviation History's Most Amazing Failures

Aircraft makers tried a lot of different designs before settling on the two-winged planes and jets we're familiar with today. Inventors toyed with the idea of a multi-winged aircraft — often fashioned from incredibly complicated structures — before discarding it. Here are some of their most amazing failures.
