At the parade they had helicopters flying by, flushing out terrorist elements causing trouble. (I suppose.)
It’s interesting to just spend a moment to look at a helicopter. They are very impressive.
An airplane uses the birds as an example of how to fly. And it adapts to the air around it, working with the atmosphere in harmony. It doesn’t try to fight it. It can be quite graceful.
A helicopter takes a different approach. It has no natural example of how to fly. It decides where it is going to go, and where it is going to be. It doesn’t try to work with the air. It levitates through pure force of will. Opposition to gravity.
This is what I like about science and technology. Humans getting to point where we can make demands on physics and force it to work for us. Where we don’t need to accommodate it.
