How does a fly land on the ceiling?

Here’s one for all the aeronautical genii in the room. When a fly lands on the ceiling, does it do a half roll or a half loop to get there? Can a fly fly inverted?

yes

I have seen him do it, at least I saw him do it in a movie. They also showed how they made that shot and it was pretty impressive even with the rotating room and all that, the man must have had the best balance and body control of all time.
