At Darwin a few years back...
A very busy mid-afternoon on DN APP, a new controller, lots of piston inbounds from everywhere plus a mix of RPT's, and the approach controller was approaching his limits and making a few bad calls until...
ATC (in frustration mode): "Will everyone just BE QUIET for a minute!!!"
The airborne fraternity shut up and waited!
After about 30 seconds..
ATC: "Ok, thanks... Alpha November Whiskey, track direct present position to Howards Springs, best speed.................." and he was okay from there!
