This is an actual 999 emergency call, from Wales UK
Control Room: 'South Wales Police, what's your emergency?'
Caller: "It's not really. I just need to inform you that across the mountain there's a bright stationary object."
Control room: "Right."
Caller: "If you've got a couple of minutes perhaps you could find out what it is? It's been there at least half an hour and it's still there."
Control: "It's been there for half an hour. Right. Is it actually on the mountain or in the sky?"
Caller: "It's in the air."
Control: "I will send someone up there now to check it out."
Within minutes, the patrol car arrived at the spot, and the conversation between the cop and the control room shows just how barmy the caller was.
Control: "Alpha Zulu 20, this object in the sky, did anyone have a look at it?"
Officer: "Yes, it's the moon. Over."
