Overheard in the Columbus Airport

I'm sitting here in Columbus, OH (free wireless!) waiting for my delayed flight to Chicago and then home in Portland.

So, I'm looking out the window and lo and behold there's a C-5 Galaxy on the runway getting ready to take off. There's a business-exec looking guy on a cell phone near me looking out the window, and he notices the plane too (hard to miss). This is what I hear him say:

There's some sort of military plane here getting ready to take off. I don't know what kind it is... but it looks sort of stealthy.

Hmmm. Stealthy. C-5. Sure...
