Ok, as I mentioned, the other day in a dram I was thinking about flying. Specifically about the sort of super-hero "think and you move thru the air" sort.
I've tagged this "geekery" because it's *such* a geeky thing to think about. And "writing" because they way I was thinking and the way in which I intend to explore the idea amounts to the sort of world building a good writer needs to do with regards to their world.
Starting assumptions:
It's possible to fly unaided.
The ability can be taught.
Without the first assumption, we don't have a post. :-)
Without the second we are dealing with a "unique" ability/situation. One which has had a fair bit of exploration.
So, now we need to define the ability a bit more. different parameters/limits will have quite marked differences in the resulting world or story.
First things that come to mind are "how fast?" and "how much?"
Being able to fly at walking speed will have results quite different than being able to fly at supersonic speeds.
Likewise, "how much?" as in what can you take with you also greatly affects the outcome.
Consider one extreme of "how much?". If people can only fly while naked, that is different from being able to carry a normal load, much less extreme loads.
