From the back of our boat in Marina del Rey, three of us watched as several (10-12) bright red lights seemed to arise from the southern sky and floated in an upward direction. In random fashion they floated up and in generally the same area of the sky, although some seemed to float off to one side (our right, as we watched) .Within 3-5 minutes, each would simply disappear. At first we thought there were clouds but we could see stars in the background of the same part of the sky.Their general motion would fit that of very large balloons yet were faster in their motion than balloons.They were not at all like flares and the general makeup of the lights seemed like each had a brighter center and vertical and horizontal refraction.There is no doubt that we all saw these lights and we recorded videos on our phones. LAX with planes taking off were clearly between the lights and our position.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
