I don't particularly enjoy, but, have you noticed how flies ( we get quite a few indoors from time to time if the cows are in the back field) will fly in 'circles' in the middle of the room?
Except they're not circles cos they suddenly change direction at a tangent over and over again.

It took off flew a few feet then landed upside down on its back. It kept doing this, each time landing upside down on its back,getting further and higher each time for about ten minutes,until it finally flew away.
