Second night of Very bright square lightsAs my wife and I were sitting on our back deck, the very next night after our first sighting, my wife said to me, "Hey, is that the same lights we saw last night?" I said it is! This time they were flashing with no sound at all behind them like last night. Also I should point out they were flashing in some kind of sequence and then they would change the sequence they would flash. Then one light then another would flash. Again in the same direction as last night (9/17/12) they went from SW to the North. It lasted the same amount of time 45-50 seconds at the same time as last night. These lights were square and parallel to each other. So when we saw them it was from their side then we could see the rear of the lights with no other lights on what so ever.
