I was taking our boat out from the marina , then one of my guests and her husband pointed at the sky , and 5 bluedots ,perfect formation

5 blue dim but bright enough dots in a a perfect straight line formation , flew together , moving perfectly together , followed each other in a perfect single file line and then slowed down and spiral into a circle and faded away one by one .
This was very frightening for me and my frinds to experience because I always make fun of people when I see something , now I have seen something bazaar with my own eyes …. And that was not something normal , the speed at which they moved and the distance from one another and formation, those dots moved faster than the speed of light . From my naked eyes it hard to believe us human beings where involved in that phenomenon….. That was mathematically impossible the details of how they moved and why so fast lightning fast …..
