witnessed a silver disk in 1970

I was 5 years old, playing football in the street with friends and dads. I remember looking up into the sky and seeing a sliver disk hovering below the clouds. It made no sound. At this age I knew what a plane was, and what a helicopter was. This was neither. It was a silver disk. I remember pulling on my father’s pants asking him what it was. He and all the other adults were freaking out. He said he did not know. It hovered for about 3 mins, then shot off like a rocket and was gone. It took me 30 years to get my father to admit he saw something and acknowledge it really happened.  Approximately 8 years ago I saw a stealth bomber fly, it had the exact same characteristics of the disk I saw as a child. Gave me the chills.
