X-56A: Breaking the Flutter Barrier

This is not an especially great video, but it has some interesting points, and it's only four and a half minutes long. Flutter in an airplane is kind of like speed wobbles on a motorcycle. Some vital part of your vehicle starts oscillating in an uncontrolled manner and if something isn't done quickly, there will be serious consequences. The start of the video shows some bad things happening, like the Tacoma Narrows bridge collapsing during a wind storm. This unmanned aircraft, the Mutt, uses a couple of itty bitty jet engines, similar to what Jet Man uses to make himself fly.
