On my way home, I captured these rather shitty photos (passenger). That little black dot in the middle is actually the biggest (diameter-wise) airplane I've ever seen in person. This thing was enormous.

You can't really tell how big this plane was in the pictures, or see much detail. However, I could, because it was flying low, and did I mention it was big? From what I could see, and a quick search on Google, it appears to be a Boeing C-17 Globemaster III, which is this behemoth used by the USAF as a heavy transport plane.
