The most important jet you can't see

(CNN) -- It may be the most historic plane in the world: Special Air Mission 26000, SAM for short. Not familiar? Maybe you know its nickname. Back in its heyday the sleek, blue and white airliner was called Air Force One.

This ain't just ANY Air Force One. SAM 26000 saw more historic events than any other -- ranging from the tragic to the hilarious. A national treasure, the airliner now sits in the Air Force museum in Dayton, Ohio.
