The United States and Qatar have not yet finalized agreements on the transfer of the luxury Boeing 747-8 'Jumbo' aircraft, which could serve U.S. President Donald Trump as one of his presidential planes, following 'unusual requests' from the Qataris who want clarifications regarding the deal details. This was reported by The Washington Post, citing official sources familiar with the matter. The report comes after the U.S. Department of Defense said the deal details had been completed. Doha is demanding a memorandum of understanding stating that the Trump administration initiated the aircraft transfer.
