flying saucer had landed on a driveway then went straight up into a pinpoint in one second

while at the drive in at a bruce lee movie I saw two "headlights" on a drive way and the bottom of the saucer lite up with several headlights or one large one, it left the earth and headed up into a pinpoint in one second, a second craft just like the first, went over head later, and did areo tricks under and around trees and at one point went over a transformer on a telephone pole on a house on a hill and the whole house blacked out of electricity at once. There was another incident in 1981 of august with another saucer up close in Napa, CA.
Date is approximate.  PD
