UFO Sighting in San Diego, California on 1968-05-31 00:00:00 - Decended into the ocean. about 8 minutes later 2 left in same direction as the 3 came in

In june of 1968, my dad, mom, brother and myself we're working at night cleaning offices. my dad told my brother and i to come to a window and told us to watch. we watched 3 green lights come down from the northwest and go down in the ocean. about 8 minutes later 2 objects came out of the ocean glowing an orange color and flew back to the northwest until out of sight. our dad told us not to ever talk about what we saw.
