I saw a flying saucer.

I was about 13 years old and I was sitting on the floor of my friend’s bedroom.  It was early in the evening; still daylight, but close to dark.  My friend was talking and she suddenly stopped mid sentence.  Her jaw dropped and she just pointed.  I turned around just in time to see a flying saucer go over her house.  This thing was very low to the ground.  You could see the lights or windows around the saucer.  It was moving quickly and silently and it appeared to be as big as her house.  We told her parents and they said it was probably a weather balloon.  I also told my parents and they too thought it was a weather balloon.
I asked her about it when we were grown and she accepted that it was a balloon.    I told my ex-husband about my experience and he told me that he had a similar experience in Baltimore when he was about the same age.  He recalls the same type of aircraft.  I am telling you, this was not a balloon.
Witness indicates that date of incident is approximate.  PD
