In 1912 Austrian tailor Franz Reichelt dove off the Eiffel Tower in a sort of real-life version of Wile E Coyote's Acme Batsuit expecting to fly or glide or do something at least pleasantly leaf-like.

He did not.

Instead, Franz did the thing that things which are not leaves do when they find themselves in the thin blue air. To quote the WFMU blog: "The film ends with men ceremoniously measuring the crater left by Reichelt."
