UFO
The main Alien craft is capable of travelling several times the speed of light.
It spins rapidly while in flight, and is armed with some sort of destructive energy
beam. Each craft seems to hold one or two Aliens. For some reason, it cannot stay
in the Earth's atmosphere longer than a few days, otherwise it overheats and explodes.
In the bottom of the craft is a small escape pod.
