AURORA, Colo. — Another unidentified plane flew low over Colorado on Tuesday morning, garnering attention from thousands below. That plane is commonly known as Air Force One.

Although technically a plane only receives the call sign Air Force One when the President of the United States is on board, the U.S. holds two models of a highly advanced plane that customarily carries POTUS.

Denver7 confirmed with Air Force officials on Tuesday that one of the U.S.’s two Boeing 272-200B series aircrafts was conducting training over Colorado skies. The plane is also commonly known as a VC-25A.

No, President Trump wasn’t aboard, but what was seen over Colorado is one of only two planes equipped to carry the most powerful leader of the free world conducting an important mission.
