Cigar shaped silver object with varying speeds, no sound heard and many witnesses.

Was a beatiful sunny summer day. My sister, brother and I along with friends were jumping rope in our backyard. My age was 10? at the time. We began to see an object approaching very slow, large silver, cigar shaped. Size was larger than any jet I have seen. It stopped directly above our 3 story house(approx 10 ft above) as if watching what we were doing. We all saw that the object had stopped, blocked out the sun, and no noise was heard. We ran screaming into the house as did our friends. Within moments everyone, including my parents, my friends and their parents, were outside to witness this object. It had begun to move slowly over the street then quickly accelerated into the sky. We all watched this for about 10 min. as the object stopped again before quickly disappearing. We still talk about this incident to this day, really terrified us.
Date is approximate.  PD
