I saw an object that reminded me of a stone skipping in the sky everytime it bounced it got higher and faster.Ok heres the best way i can describe this...my brother,sister, my friend and I were outside when i looked in the corner of my eye and saw an object in the sky my first thought was that it was a black plastic bag or a kite swaying back and forth with the same heigth. It was weird i questioned it to myself i dont know about the other three because it was daytime so i didnt think it was real so my brother brought out his camera and it continued to sway back and forth it looked black and shiny, moving direction quick and a couple times it stopped and froze. So my sister and i were tripping out on this than my brother and my friend went into the house and i told my sister i was going to get my binoculars for a closer view so i went inside looked around and couldnt find them so i sat down on the couch and kind of doubted what i was looking at. Then my sister said "what are you doing arent you getting your binoculars" then something inside me told me to go check it out again so i went outide to see where the object was reminding you it was daylight so i walked outside by myself and my sister was inside for some reason so i scanned the sky looking for that object floating around it was gone but i kept looking for some reason looking in the same spot than suddenly out of knowhere i see a black disc shaped object diving, now at first i thought it was a bird swooping but that changed after i saw it go up again repeating the same movement but getting faster and higher bouncing in the air it amazed me and still is ,it reminded me of somebody skipping a stone in the sky down than up and everytime it would get faster and higher and each time, i heard no sound then it was gone i think it was building its momentum with our atmosphere to get back to where it came, even my brother came out and i tried to point it out but it was too fast im still wondering about this but i know for a fact what i saw was real and not my imagination i wish somebody was there with me to see that hopefully there will be a report about this, ! i did se e a couple helicopters circling around that area after i wonder if they got a report but all i know is what i saw i will never forget.
