The IP pretty much beat that into our heads during the sim. Both he and my onwing back in HTs talked about the black hole, doesn't sound like fun at all.
It's definitely something to be respected, but honestly, I've found, both for myself and nuggets I've been flying with, you don't truly understand why it's a big deal until you're in it. Of course, the problem with that is that you hope your copilot is with it enough to see it happening and is ready to pull power. I had my first (and only...knock on wood) experience in the middle of my first cruise, and it was very "educational."
