Mounting evidence seems to point to an attempt by president Donald Trump to flee to Scotland on January 19, the day before Joe Biden's inauguration as the 46th president of the United States.

British and American media outlets are independently reporting officials at the Glasgow Prestwick Airport 51 km from Glasgow being told to expect the arrival of a U.S. Air Force Boeing C-32 aircraft on January 19, the day before Biden is sworn in as president.

The C-32 is the military version of the Boeing 757-200 mid-size, narrow-body twin-engine jet civilian airliner. One of these planes is the official aircraft of the U.S. vice president.  This plane is called Air Force Two.

The U.S. president flies in Air Force One, which is a modified version of the Boeing 747-200B and is called the VC-25A in Air Force use.

"There is a booking for an American military version of the Boeing 757 on January 19, the day before the inauguration," said a source at Prestwick airport to British media.

"That's one that's normally used by the Vice-President but often used by the First Lady. Presidential flights tend to get booked far in advance, because of the work that has to be done around it."

Air traffic controllers at Glasgow Prestwick Airport will receive details of the arrival of a plane with a special U.S. call sign weeks in advance.

In November 2014, Trump signed a partnership agreement with Prestwick making it the Scottish base for all Trump aviation operations in order to service his Trump Turnberry golf resort 20 miles away.

Trump has developed strong ties to Scotland, partly because of his Scottish ancestry and owning Turnberry and another golf course in Aberdeenshire. Trump's mother, Mary, hails from the island of Lewis.

American media is reporting several U.S. Air Force planes have been spotted carrying out surveillance above the Turnberry resort in recent weeks, which is standard operational procedure preceding a presidential visit. Scottish media seems to confirm these suspicions.

"The survey aircraft was based at Prestwick for about a week," said one source to the Scottish weekly newspaper, The Sunday Post. "It is usually a sign Trump is going to be somewhere for an extended period."

While these rumors make for intriguing news, the fact is Trump and his entourage will violate the tough new British COVID-19 restrictions were they to fly into the country this month.

First Minister of Scotland Nicola Sturgeon on Tuesday announced Scotland will be placed in lockdown for all of January, with a legal requirement to stay at home.

It's also not clear how Trump, as a private citizen, can fly back to the U.S. after January 20. Trump has repeatedly said he plans to run for president in 2024.

Biden's transition team said Trump's presence or non-presence at the inauguration won't affect their plans.
