“If it is private wise-asses they’ll stop doing it when they keep losing their drones.”
Private wise asses don’t have drones capable of flying 100 miles out to sea, loitering for 90 minutes, and then flying back home.
My guess is these were launched from a sub in the area.
Apparently not one of ours.
Or from a ship over the horizon, or dropped from an aircraft.
Without statistics regarding size and speed, assumptions are useless.
