Fleet of mysterious lights appear above sea near North Carolina filmed from a ferry

William Guy was on a ferry traveling from Ocracoke Village to Swan Quarters North Carolina on September 18, 2019 when he noticed a fleet of strange bright lights in the sky on which he started to record the strange event.


William said that that there were about 25 people on the ferry with him that have seen it too and they also recorded the fleet of lights and none has ever seen it before.

We may assume that these lights are not flares since no source can be found in the entire area that may have fired flares.

What could these lights have been?
