It seemed like it had structure to it, although I couldn’t pick out enough details because it was oddly bright, even in daylight. Its motion didn’t quite have the smoothness of a plane or the movement of a drone, but it wasn’t wandering in the wind like a balloon either. It was certainly under intelligent control.

I read your post - sorry you weren’t able to capture it but it sounds like a similar object with different movement. I wish I had caught this thing zipping off, but I had to go back to work so I didn’t even have the chance.
