Obviously a drone should not be in the air when full size are around.
But, when all the choppers were grounded, what's the problem with flying a drone then?
So clearly a drone should not be a problem until full size arrive on scene, right?
So when was the drone first seen in the area, before or after the helicopters arrived?
I can just imagine it, some observer on the ground reports a drone and the fire control officer sounds the alarm before the helicopters even arrive and grounds them.
Hysteria like I said...
