Two white, spherical shaped craft flying Eastbound over Ventura Boulevard from Sale Avenue. Very slow, maybe about 25mph and at about two thousand feet above ground altitude. They both maintained a fixed distance from each other as they moved and going in the same direction. Sid not speed up or slow down during the minute or two during the observation. These were not drones, fixed wing aircraft, balloons, or helicopters. They looked like two golf balls flying in formation.
