Saw a large sphere above the cloud bank, then four smaller came to it wherein the objects accelerated to the cloud bank in formation

My siblings and I were watching a movie on a Saturday afternoon when my Dad, who was cleaning our pool, came into the Den and tried to get us to come outside to see UFOs. I was the only that went. As I stepped onto the pool decking I could see a spherical object, stationary in the sky. The sky was a bright blue that day with a cloud bank all around the horizon. The object was large enough that it looked black around the edges and highly reflective in the center. I realized that this was due to the extent of its’ “shine.” I noticed 4 smaller spheres (did not appear to be shiny but I assumed that was due to their smaller size.) I had the impression the main sphere was huge. All four came in at the same speed from 4 equal distances and stopped at the same distance from the main sphere. They all accelerated together and were gone in about 2 seconds behind the cloud bank. I have never reported this because I didn’t want to be labeled a “nut.” My Dad saw similar but just the large sphere. He had stayed inside trying to convince my Mom what he saw. I was 17 yrs old. I can still see this clearly in my mind.
