- This is just intuition speaking.
-
- The gross aerodynamic properties of a boomerang are such that it will return
- to the point from which it was launched with (about) the same speed with which
- it was thrown. Tossing one off a moving train is exactly the same as ground
- launching it with a howitzer. That means that some guy back in the dining car
- is going to be pelted by a boomerang.
-
- Friction has very little to do with lift. The only purpose friction serves is
- to make an engineer ruin a perfectly good airplane by putting an engine on it.
