Chop did you personally witness this?
No.
Or are you guessing about the consideration model flyers give emergency service helicopters doing their thing ?
Yes.
I could well imagine... Drone pilot flying over a site and being told to land because a helicopter is en route.
Drone pilot asks "how long until it gets here?"
He's told twenty minutes
Drone pilot says "I will land in fifteen minutes then."
Get's reported for refusing to land.
Helicopter lands twenty minutes later without incident. (Drone has already landed 5 minutes before because the pilot heard the helicopter coming).
Sounds like a police state to me.
Just guessing though...
