This two-reel short subject from Universal offers a lot of clips from the forty years since the Wright Brothers had gotten off the ground at Kitty Hawk. There are shots of the Wrights; of Glen Curtis; of Eddie Rickenbacker, Igor Sikorski, aviation stunt men for the movies, autogyros and flying machines that didn't fly and.... so forth.
Including the tragedies, the lives lost, bodies injured, not just the Hindenberg, but the Akron, which wound up killing three members of the ground crew, but also the Luftwaffe.
All of which leads to a vaunting of American air power, particularly the Naval air force.
