Welcome to the first installment of Bat-School, where I will periodically pose an essay question about — or gave some insight or background into something related to — our favorite guardian and protector, the Batman.

I won’t say much about this first lesson in case you’re one of the seven people in the world who haven’t seen The Dark Knight yet.

But there’s a certain sequence in Hong Kong that involves something referred to by Wayne Enterprises CEO (and Batman’s gadget guru) Lucius Fox (Morgan Freeman) as “Skyhook,” which is a nickname for the Fulton surface-to-air recovery system.

The sequence has gotten cheers from every crowd I’ve seen it with.

(Four so far and the fifth already schedule for this weekend, in case you’re wondering/counting.)

And go see The Dark Knight if you haven’t already; I’m taking my time on my formal review and I’ll put it up next week when I feel like I’ve talked about everything that needs to be talked about, which is a lot.

It exceeded every one of my outlandish expectations. It did so in ways I still can’t believe, and went to places I never thought we’d be lucky enough to see in a Batman movie.

Much more to come.

Count on it.

P.S. If you’re reading this and you have an MC-130, I’d like to get some people together next week to try this. I’ll provide the pizza and the Pepsi.
