Seen that before, but that pop open because when u download 4 add-on game (broken steel, Arch, Pitt, point lookout) it start get glitchy if u have low memioers like 6.6 g bites on ur hard drive.
Same with me one i came out of Agathas house and a random robo-brain flew out of no where i reloaded my game just to make sure it wasn't there at first.
I know exactly what it is!!! It's a parody on "Lost"'s Monster. Big Black flying something of unknown origin. It supposed to quickly fly over the Wasteland in front of a player, but sometimes get stuck in the mountains.
