protectthehornet, wow. So familiar. Except I was in place of that DC10, it wasn't PHL, and it wasn't one heavy iron against another. The lesson I learned was — if it looks like you're erring on the safe side, just go ahead and err on the safe side, don't assume that the controller is any more focused and caring about your ass than you are (and as the recent events show, he might as well be chatting with his girlfriend or showing off to his kid). Say unable and vacate the effin runway.
