UFO Sighting in Boston, Massachusetts on 2017-06-25 00:00:00 - What i unexpectedly saw, changed my disbelief in extraterrestrials

I was riding my bike with my friends down the back streets of my town. one of my friends looked up and thought he saw drones, so he waved up. once we started to get a better look however, it was very clear that they were not drones. i got out my phone and took video of the strange phenomena as we just sat in awe. they were silent and going sideways. they were big and very high up and were a silver color. there were three of them and they were in some triangle shape. it only lasted about 2-3 minutes before they were gone. i have never seen anything like it, and i certainly cannot explain it.
