President Donald Trump on Wednesday is taking the first ride on the newly retrofitted Air Force One 747, which was donated by the Qatari royal family. Trump, taking the retrofitted jet to North Dakota, touted it as "maybe the greatest commercial plane ever built." "I said to Boeing, 'What's the best one?' They said this is the best plane ever built, and you're going to have the privilege of flying it, and I have a privilege also of flying it," Trump told reporters before boarding the jet -- which is approximately 14 years old -- at Joint Base Andrews. The Qatari-gifted jet worth $400 million raised questions from some lawmakers and ethics experts over the unprecedented foreign gift. But Trump on Wednesday gave credit to the Qatari government. "Frankly, we couldn't build a plane like this because we wouldn't be willing to spend the kind of money necessary. They spent top dollar," the president said.
