From the Boston Herald - a firecaptain thought he saw a drone and canceled a medevac request.
The only video is of a planes flying over, not drones.
For most of this the oddity is that most drones don't need navigation lights at all. They can be bypassed or disconnected. If these are drones they are being operated beyond the line of sight of the pilot they will have a video feed to show the pilot what the drone is doing; no need for navigation lights.
