The UFO has a crew of small red-eyed aliens inside of it. The easy way to see them is to crash the UFO, they can be seen in the debris. If you want a closer view, follow these steps:
Take off in the UFO and start flying straight up. Cut the engines completely. The UFO will stall and begin gently falling. Try to keep the UFO pointed straight up. If done correctly, as the UFO falls, it will fall down onto the camera and you will get a view inside the craft where the aliens are seated.
