Hey Donnie,
Yeah, I have seen that video before. I don't pretend to have any authority in forensic analysis, but here is my personal opinion.
Wide lenses have a way of flattening out depth. In other words, you can't really determine how far an object is based purely on what you see, instead you judge distance in relation to other objects in the frame. This is because of the lack of depth of field (everything is sharp) and the widening effect of the lens pulls everything pretty equally.
This image is a good example of what's known as "forced perspective" where you want to believe objects have a different relationship because your mind pulls them around:

When flying, when there is no ground to anchor objects, this is especially true. Your mind will place objects in relation and then judge the object's size and dynamics accordingly.
So how does this apply to the video?
First of all, a small object close to the lens moving slowly will look like a much larger object further away travelling at great speed.
You can also use the amount of motion blur to estimate distance. There wasn't a great deal of motion blur in the object. If it were moving at 1000MPH there would be much more.
So in my personal opinion, it's likely this was a small creature flying close to the lens. The trajectory is interesting as it appears to follow the ground path, but I think this is just a coincidence.
