Was playing with kids outside my family home. was used to the goodyear blimp lights, planes and other aircraft over palos verdes. parents were inside home having a party and the kids - about 5 or so were with me outside. this was around 6;30pm or 7pm. all at once we stopped playing and were fixed looking across the street. two all encompassing blue lights flashed. or rather we saw two blue flashes of light which seemed to illuminate the whole street and all the homes. no sound and did not think to look behind us and up at the time. really odd experience.
