Air Force One, carrying President Trump and first Lady Melania Trump, just took off from Joint Base Andrews. They're on their way to Florida.

The plane took off as Frank Sinatra's "My Way" played over speakers.

While it is typical for outgoing presidents to depart Washington on one of the airplanes maintained by the 89th Airlift Wing of the Air Force, it is not typical for that final flight to be officially called Air Force One, since those craft only have those names when the President is on them.  

An outgoing president's final airplane flight is usually called a Special Air Mission. Trump’s predecessor, 44th President Barack Obama, left town on a flight officially known as Special Air Mission 44.  

But Trump’s early departure from the White House means he’ll still be president for the entirety of his flight to Florida.
