The presidency explains why presidential jet remains in london

I think there may be some confusion here!

The Presidential Jet, also known as Air Force One, is the official aircraft of the President of the United States. It is a highly customized Boeing 747-8 aircraft that serves as a flying White House, providing a secure and comfortable means of transportation for the President and their staff.

However, I'm not aware of any instance where the Presidential Jet has remained in London for an extended period of time. The aircraft is typically based at Joint Base Andrews in Maryland, near Washington D.C., and is used for official trips and events within the United States and abroad.

If the Presidential Jet were to be stationed in London, it would likely be for a specific event or meeting, such as a G7 summit or a meeting with the British Prime Minister. In such cases, the aircraft would be used for a short period of time and would likely return to the United States afterwards.

It's possible that you may be thinking of a different aircraft or a private jet that is temporarily stationed in London. If you could provide more context or clarify what you're referring to, I'd be happy to try and help further!
