“AirForce One” does not actually refer to a single aircraft, but ANY US Air Forceplane carrying the US president.
“空军一号”并不是特指某一架飞机，而是美国总统乘坐的任意一架美国空军飞机，均可被称为“空军一号”。
So, whatexactly is the story behind Air Force One?
那么“空军一号”到底有什么特殊之处呢？
Well,the very first plane outfitted specially for the president was the DouglasVC-54 sky master, a non-combat military aircraft.
其实，专门为总统配备的第一架飞机为道格拉斯VC-54型飞机-飞行大师，这是一架非战斗军事飞机。
It wasoriginally used by President Franklin D. Roosevelt, who notably flew on it tothe Yalta Conference between FDR, Winston Churchill, and Joesph Stalin.
它最初由富兰克林·罗斯福总统使用，罗斯福、丘吉尔、斯大林乘坐该飞机去参加雅尔塔会议。
Theplane was also later used by President Harry Truman, and nicknamed “The SacredCow”.

然而如今的空军一号并不像母牛，更像鹰眼高科技防御系统。
Accordingto the White House, the current models are able to be refuelled in mid-air,meaning that they can fly an unlimited number of miles.
根据白宫信息，该架飞机可以进行空中加油，这意味着无限制的飞行航程。
Thenavigational and communications equipment on board is also shielded from anelectromagnetic pulse, which in most other cases would disable any otherelectronics in it’s wake. In fact, Air Force One is able to serve as a commandcenter for the president.

But theplane is also incredibly comfortable.

But ifthat’s not enough, Air Force One is frequently flanked by additional planes,which carry any extra cargo the president might need in remote locations.
