US President Donald Trump left Turkey after a NATO summit last month in a carefully planned secret operation, rather than following protocol, to avoid an assassination attempt. Trump was hidden in an airport food truck and then secretly flown onto a military plane, The Washington Post has learned . However, after the NATO summit, he announced that he would use the “former Air Force One” rather than the Qatari plane, citing security concerns. In Ankara, Trump boarded an old Air Force One in front of television cameras. But minutes later, he was secretly transferred to a smaller plane, a U.S. Air Force C-32A, using an airport catering truck used to deliver food and supplies before flights.
