"the drone’s presence prompted four sailors to demand the operator obtain permission from the ship’s command."
Why do that when the ship's command could have sent one sailor to extend permission?
"This fine states that the drone flight activated the warship’s anti-terrorism measures"
Maybe a better understanding of the nature of terrorism is in order?
This guy has a drone - they have a warship. How do we know they aren't about to launch a salvo on the city? Would they have had a similar reaction to a kite?
I would like to know how the anti-terrorism system is triggered. My guess, it's someone saying "There's a drone!" (but in French) and Chicken Littleing their way along the ship. But thanks to this over-reaction actual terrorists have more insight into problem-causing efforts they might make. Good Job! Attack the good guys and tell the bad guys what they need to know.
