lights moving in the sky 7 landing in Oakland over coliseum & airportblinking light emitting red/purple/gree/white at different times. At first it was one then I saw another one that was bright white at first begin to move and change colors. This has been occuring every night since that original night moving into the 7th night. The first night when we were watching it, my cell phone rang at 5:00am when I answered it, a very loud beeping noise came out of it. On Friday 10/04/02 we actually saw the lights come all the way down & land and this time there was about 20 moving throughout the sky and about 10 that landed.It was actually pretty frightening, becauause we had been studying them & their movement, seeing them land was a bit too close for comfort.An interesting thing is that we saw them land inside the Oakland Coliseum & the Oakland airport.
