OCWATO separation standard
While going through my course in Cornwall (Canada, that is). One of my fellow students made the following remark after being rebuked while on a non-radar exercise.
He was supposed to use 10 minutes between airplanes but when one declared an emergency, even though there was only 8 minutes he "broke vertical" and got the emergency aircraft down.
When the instructor told him he'd had a sep-loss, he just yelled:
"OH! COME ON!!! WHAT ARE THE ODDS??!!"
