Those men are not running in terror from an alien spaceship or a time traveler’s pod arriving from the year 2250. It’s just a tetrahedral kite, developed by Alexander Graham Bell in an attempt to build kites large enough for people to ride in. Which, you have to admit, sounds awesome.
The idea was also to make them so a motor could be installed, thus creating the first manned aircraft, but the end result was just a bunch of admittedly cool-looking kites that could only ever possibly be piloted by G.I. Joes.
