I saw three flashing lights in the sky over Melbourne Beach. They moved erratically and kept flashing the whole time that I saw them. I was looking out the window to see the rain when I noticed them. I checked on them from various windows in my house and they were the same from each one. As I was watching them, they just vanished.My husband and I also had a similar sighting on Saturday (10-20-2012)evening. We were sitting at the beach on the deck and looking south at the lightening storm. Two flashing lights also appeared and did not seem to move as a plane lights would. They also just vanished after about 5 minutes.
