Approx 1984 during a winter month, I was driving NE on Rio Del Mar Blvd in Rio Del Mar CA (Aptos, Santa Cruz County) with 3 housemates. The time of day was close to sunset. To my left over a house there was a Flying V shaped craft with approx 4 beams of white light emanating from the base of the craft on and around the house. The lights moved independently and were similar to very bright spot lights, not diffusing or getting wider. The craft was maybe 100 feet in altitude, was grey in color and was traveling at what appeared to be 3-5 mph. I'm guessing that the wingspan was approx 100 feet wide (more or less). I stopped my vehicle and observed the craft passing me and when it was at about at a 10:00 angle from my drivers side window it slowly disappeared. I was too choked up to tell my housemates who were in the car with me. I had posted this event maybe 20 years ago and I noticed that my documentation had somehow disappeared from the internet.
