President Obama ended his eight-day 20,903-mile  Asia Trip on Tuesday, jetting back to the U.S. via a re-fueling stop at Elmendorf Air Force Base in Anchorage, Alaska.

It was during that stop that the Associated Press' Carolyn Kaster snapped this awesome photo of the underbelly of Air Force One.  We reached out to Kaster to talk about how she got the shot -- but haven't heard back yet. We'll update this post with her thoughts if/when we get them.

In the meantime, here are a few other terrific Air Force One photos we came across.
