The White House of course has scenarios in place in case of nuclear war or some other disaster to protect the President, and they include a so called "doomsday" airplane.
The Daily Mail quotes an ABC News report that said the $223 million plane is equipped with thermo-radiation shields in case of a nuclear strike and is also protected by an electromagnetic pulse shield.
It is on standby 24 hours a day, 365 days a year -- its crew always nearby, ready to jump into action.
The last time it was used was during the 9/11 terrorist attacks.
It can be refilled midair, so it doesn't have to land for days.
The plane has enough electronics that the President can run the nation from 30,000 feet above Earth. People on the plane can communicate with anyone on the ground.
Even nuclear submarines can be reached underwater when a five-mile long cable is extended out of the back of the plane for reception.
'[We] drop is down and [it] transmits coded message traffic to U.S. submarines,' Captain W. Scott Ryder told ABC News.
One drawback -- the bathrooms are tiny, with sinks but no showers.
