Unknown object moving across sky zooms away

Upon arriving at my wife’s salon, while walking in, I happened to look up in sky and observed something going across the sky. I initially thought it was a balloon. Something then didn’t feel right which led me to believe it was something else. Perhaps a drone. I tried to continue filming on my iPhone 13 max, however I wanted to see with my own eyes so at that point I stopped filming.
As soon as I stopped filming I saw two flashes. Then a few seconds later two more flashes. At this point I lost it and began recording again looking for it. I couldn’t find it. In the 14 second video after going inside and showing my wife and oldest daughter, my daughter asked did you see that? What she referred to was the very first second on the 14 second video.
It appears what ever I saw seems to Zoom down and away at high acceleration beyond anything I have ever seen. I would never have thought much about it until I saw that portion of video and felt the need to report this. I am a police officer in Massachusetts and would like to stay anonymous to the public. Thank you for your time.
