He was full speed and had built up momentum. Going fast would be an understatement.

While almost as tall as a person there is not much weight here. As you can see in these photographs when fully stretched out there isn’t a lot to focus on.

Above he looks paper thin.

In a shot like this if you don’t grab focus when a wing is in the downward motion…well you don’t get any of the series of shots.
Pretty much that means you miss more then you get.
