eli5: Why is it not possible to build bird-like attachable wings that account for body proportions to allow humans to fly or glide around?
In: 2102
Humans are much too heavy for bird-like attachable wings powered by muscles alone. Our bones are too dense, among other problems.
Were we to construct a large, air-filled habitat on the Moon, it might be possible for a human to fly in such a manner there. [This has appeared in science fiction at least once.](https://en.wikipedia.org/wiki/The_Menace_from_Earth)
