Saucer over house in Amherst NY 1966 quiet whirring sound

I am reporting what I believe was a UFO sighting I had when I was a child It was in the mid 1960’s around 1965, 1966, or 1967 I was about 9 or 10 at the time.
It was mid august about 2 weeks before school started.
My parents, younger brother, and I were living in Eggertsville which is part of the Town of Amherst NY near Windermere Boulevard elementary school.
It was late evening full darkness my brother and I were looking out our bedroom window. Looking east we saw airplane strobe lights, stars, all that we saw on a regular basis. The night was clear.
Then I saw a red dot of light which zoomed from right ( South) to left (North) and lower. Very far away then it went left to right and lower again. Then it went to the left out of sight.
A few minutes later I heard a low whirring sound, sort of like a washing machine spin cycle in the distance, but it sounded stationary and above our house.
I went out the front door and looked up followed by my father, he said to get the camera, but it was out of film.
What I saw was about 30 to 40 feet wide and about 15 feet high with an amber row of square windows around the center. It was saucer shape, the same angles on the top 1/3 as the bottom 1/3 with the window section also about 1/3 high and straight vertical. It appeared flat on top and bottom. I saw a ring on the bottom which rotated a little. It was about 20 feet above our single story house.
Then I went back inside the house after what seemed a few minutes I did not see my brother or parents I felt alone in the house. After several more minutes the whirring sound left and must have gone to bed. My brother or parents do not remember this event. I am looking for any one who may have seen something like this around that time.
