Not quite sure why we would mark milestones of powered flight in a HG forum

Non powered flight has a few firsts to offer, too. Otto Lilienthal, Octave Chanute and Percy Pilcher spring to mind. But there is also George Cayley who built a glider that was flown as early as 1853. I like to think that there are more like the first stained flight in a thermal. Or the first passenger flight in a glider.
