OK, guys, I'm trying to be serious.

Why do Delta pilots routinely ask for a wind check? Is it a procedural requirement? Does it have to do with the particular aircraft you're flying? Perhaps some type of limitational requirement? Is it just an old military habit? The rest of us smile every time you guys as for a "wind check," but if there's a good reason, I'd be curious to hear what it is. Enlighten me!
