Multiple Amber-Red lights over South Boston heading North over Boston-Logan International Airport.It was about an hour after sunset, I was getting relieved from watch and happened to look out of the window to the ESE and caught 3 amber-red lights heading North towards Boston Logan International Airport at approximately 1,500-2,500 feet in a triangle formation; one of the trailing lights made a sudden maneuver and crossed the other that was trailing and proceeded North; As the lights crossed in front of me and headed away, the lights faded out as they were closing on the the airport.It was after I had lost the first three that I looked back to the South and saw more lights in no particular formation, but on the same heading and altitude, about 15-20 went by in total. By the time these showed up, 5 other witnesses had spotted them from below my vantage and confirmed what I had seen. On the level I was, there had been another witness as well. Also, of note was a cruise ship that had departed and been in the channel fairly close by at the time.There were no clouds, but I could not make out any stars prior to or during the event; winds minimal and temperature mild.The lights moved at a steady speed, approximately 50-70 knots, a steady altitude, and in full unison towards the North. No sounds could be heard emanating from them, or other lights. Shape and exact size could not be determined.The lights/what they were attached to were clearly under intelligent control whether it is ours or not I can not say.I was able to get two cell phone videos but they did not catch very well the extent of what I saw.I did notice that after all of the lights had passed, a helicopter had followed close behind and proceeded towards the North, but avoiding Logan airspace-it did not appear military and was plainly visible. It should be noted that these lights continued through Logan airspace without regard to it.Of note is that a line of landing airplanes could be seen coming from the North and landing at Logan-very close together and I had not seen them do this for the two months I had been here-once the objects passed, some planes had refrained from touching down and began to gain altitude to continue their flights.
