I was on the way home with my mother and seen the ship 20 feetp above us and asked her to pull over

The object or ship was a short cylinder about the size of a helicopter with cubes coming out of it. It was more wide than it was thick. It slowly flew over us right above the pine trees and disappeared over the tree line. It was a single object by itself. I asked my mother to pull over so we could watch it then while looking at it without taking my eyes off of it I asked my mother if she could see it too and she said yes. After it was gone I said let's go and we acted like it never happened.
