U.S. President Donald Trump faces questions about the security of his new Air Force One plane gifted by Qatar, after he took an older jet home from a NATO summit this week.

The billionaire president has barely been able to contain his excitement over the retrofitted Boeing 747-8 aircraft, which took him to Ankara on its maiden trip outside the United States.

But then Trump abruptly announced in Turkey that he was sending the luxury plane on ahead to a British airbase ¡ª saying it was so U.S. troops could tour the plane donated by the Qatari royal family.
