President Trump switched to the old Air Force One after leaving a NATO summit, with reports suggesting a security precaution was a factor in the decision to use the older plane when departing Turkey. The president initially used the old Air Force One but may have switched to a different jet, possibly the Qatari-gifted plane, later in his trip. The exact circumstances and details of the switch are not entirely clear, with some outlets reporting conflicting information about the president's travel arrangements.
