https://en.wikipedia.org/wiki/Otto_Lilienthal
Yes, as an "American", (capital A), have heard of Lilienthal and his success with GLIDERS.
Uh, "Grammar Nazi" detected. Try to write a single sentence in German without Google translator.
Hahaha good one!!
That's a glider. Any machine is going to be heavier than air...
Yes, his death was the principal reason the Wright Brothers designed their airplane with the vertical stablizer in the front of the aircraft rather than the modern design in the aft (tail). Because if a stall happened, the nose of the Wright flyer would stall before the wings and drop, causing the airfoil to regain lift, thus preventing a crash and subsequent death.
