It happened today at 1:56 pm. I was at 1-75 North Bound. The sky was clear, no clouds at all. I saw something white moving West to East super, extra fast. I have no cars in front of me then I slow down my car so I can see the object better. I know that closed there is a FLL Airport and I thought it was a Learjet. It was like a cigar shape or maybe a bullet style. Then I slow down more and saw it changes from white to gray and then disappeared in front of my eyes. I tried to find it but it was gone. I did not take a picture, everything was so fast and I was driving.
