Did anyone else think that the hatch door looked like a "flying saucer" when it was arcing over to crash near the beach? For an instant, I thought that they were going to imply that releasing the magnetic field freed a captured UFO and start a whole storyline about how protecting Earth against an alien invasion/attack was the real purpose of Dharma and the magnetic field equipment that Desmond shut off was the means by which the alien craft was prevented from flying.
