Ah, the good ol' HASEL check!
Only works if the other guys are looking too.
I've had a few close calls too. I was doing a circuit once at a controlled airfield, reported downwind and was cleared to land. 15 seconds later, a company Cheyenne flew over top of me no more then 200 feet vertical separation. Next thing, the controller calls me and asks me what I was doing? I'm like, excuse-me? Don't blame me for your mistakes!
Anyways, I got on the ground and talked to the pilot of the Cheyenne, and he agreed that ATC messed up on that one. The other pilot knew I was on the downwind leg because ATC cleared me, but he couldn't see me so he decided to fly a few hundred feet higher then normal. Smart move!
