Uploader comment: Me and my brothers saw a couple of... something, in the air a couple of months ago, I tried to upload these pictures back then, but it failed for some reason.
We have no clue at all as to what it could be. It kind of looked like planes from one angle, but not at all from another. They were flying around in the air and sometimes it sort of looked like they blended in with the air, or went transparent or something. First it was only about four of them, but then more joined them.
