a person in midair doing a back flip.
A man is in the middle of doing a high dive in the Olympics.
Being midair doing a back flip does not tell us if the man is in the beginning, middle, or end of the process, and just because he is doing a backflip does not mean he has to being doing a high dive in the Olympics, as someone can do a back flip on their own, for fun, on a trampoline, or many other ways that are not exclusive to an Olympic event.
