As soon as you start the level, turn around and zoom in on the Phantoms. After watching them for a while, they disappear into the clouds and spin out of control. One Phantom could crash onto a platform below. The other two will keep on falling until they hit the bottom of the level. A logical explanation as to why this happens may be because Bungie only planned for them to travel a certain distance, and upon reaching the end of their route, the game physics take over.
- Sometimes, when spinning, an Elite will fly out, and then disappear in barely a second.
