We were playing beach volleyball on a lighted court at dusk when a team-mate yelled "hey look at that." We all looked up and saw 4 bright red lights roughly equidistant from each other, 3 of which were in a line from west ascending to the east at about a 45 degree angle and travelling at the same speed. Original position of lights when first sighted * * * * Final position of lights when last seen * * * * The second red light from the left was lower originally and out of alignment with the rest of the lights. It then changed direction ascending until it reached the proper position to be in alignment with the others lights as shown above. A few people wondered if it might be a group of UFOs but no one could say for sure, but everyone was quite amazed at what was happening. A few people said they could not see the lights clearly without glasses. We were at least 12 players and most saw the lights. We had to continue our game and after a few more points I looked again and the lights were gone.
