Ah, the sing-songy refrain of controllers working airports with conflicting departures...
Some years ago I was employed at at TRACON wherein, at roughly 0617 every business day, there'd be exactly the same mess to sort out. I'm not talking a departure rush, per se... Rather, it was a small number of fast and moderately fast aircraft departing three different runways and making me work for my pay before I was finished with that first cup of coffee. Twenty minutes later there'd be an actual departure rush, but no 15 aircraft on freq at the same time ever made me work as hard as those three first thing in the morning. Guess it made the rest of the day seem easier anyway...
'Tis the same, world-wide, ain't it!?!
