ABOARD AIR FORCE ONE/ WASHINGTON, Feb 19 (Reuters) - U.S. President Donald Trump said on Wednesday he was not happy with planemaker Boeing BA.N and his administration might have to go a different route with Air Force One planes.

The Air Force One program may be further delayed until 2029 or years later, a senior administration official said, citing supply chain issues and changing requirements, after the White House said the project failed to deliver a new plane on time over the weekend.

President Donald Trump says he is considering buying used Boeing aircraft — perhaps from an overseas seller — to use as Air Force One when he’s aboard, as he fumes over the U.S. plane-maker’s delays in producing two specially modified ones for presidential use.
