[...]The other thing
that bothers me is that *both* pilots were oblivious to being on the
wrong runway. When I fly the Pilatus (private charter) the checklist
requires us to set the heading bug on the runway - it's part of the
line-up check. I'm sure Comair has a similar checklist to the one we
use, and I'm amazed something like this could happen.

If you pull onto the runway and set your bug to the runway you THINK
you're on without verifying it against the compass or some other piece of
gear, you haven't improved your safety one bit. OTOH, I'd be surprised if
the Comair didn't have a number of additional checks to make, such as GPS,
that should have exposed the error prior to rolling.
