Power and strength are also themes. The ability to fly shows that the people have an inner power and strength that can't be easily subdued. It's a way of expressing that they are more than what their oppressors might think, and they can rise above their situation.
I'm not entirely sure as the story isn't widely known to me in a very specific sense. But generally, there would likely be the people who can fly. Maybe there are leaders among them who guide the others in using their flying ability.
One main theme is the connection with nature. Fly fishing often takes place in beautiful natural settings, and the stories often explore the relationship between the angler and the river, the fish, and the surrounding environment.
As I said before, if it's about the Wright brothers' story, then Orville and Wilbur Wright are the main characters. They were the ones who worked hard to make the first powered flight possible.
Since I don't know the exact 'the man can fly story', it could be an ordinary man who suddenly gains the power to fly. So, the main character would be this unnamed ordinary man.
In 'the fly original short story', it often involves a man's encounter with a fly in a rather strange or thought - provoking situation. Usually, there are elements of the man's reaction to the fly, perhaps his attempts to get rid of it or his observations about it that lead to some deeper meaning or self - reflection.
The main elements include the anticipation that is built up before the 'fly' is introduced. This anticipation makes the appearance of the 'fly' more impactful. Then there's the struggle that follows the discovery of the 'fly'. The characters may struggle with themselves, with each other, or with the situation at large. The resolution of how they deal with this 'fly' is also an important part of the story.
Since the 'fly back to me story' is not defined clearly, it's impossible to determine the main characters. It might be a story with a lonely traveler as the main character and a spirit in the form of a flying creature that flies back to him to guide him on his journey. Another possibility is that the main characters could be a young girl and a fairy that has the ability to fly and always comes back to the girl when she is in trouble.
The main theme could vary, but often it's about something that spoils an otherwise perfect situation.
Another theme could be adventure. Flying is often associated with adventure, whether it's the bird exploring new areas or the new pilot facing new challenges. It's about stepping out of one's comfort zone and having an exciting experience.
The main character is the scientist who conducts the ill - fated teleportation experiment. And, of course, the fly which accidentally gets involved in the experiment.
