Me and my children were driving on Okeechobee road towards SE 4 St, when my son pointed out that there was something in the sky. I looked and saw an airplane, I turned to him and said " ok I see the airplane too, (he's eight years old) he screamed at me again and said no look higher and that's when I saw an Oval dome shaped aircraft with fire coming out towards the back of the craft. I could not believe my eyes so I started slowing down the speed of the car to get a better look at it.. the driver in back of me wasn't to happy and started to pass me on the right hand side, when she did, she saw me and my children looking at the sky and she also saw the object we both started slowing down traffic trying to figure out what it was. It kept flying down Okeechobee with fire and smoke exiting the back of the craft, until it made an abrupt turn right and started going down 8 Ave East of Hialeah. I kept following it myself and four other cars that were trying to get it on their cell phone cameras, but as I was looking at the fire and smoke had already stopped and all of sudden disappeared, like they turned a switch so we couldn't see it anymore. My kids and I were excited but scared my son kept asking me "what does this mean??" I said... I don't know.Ever since then I have found some footage that looks exactly like what I saw in youtube, under UFO flying over Miami.
