A new report from the Wall Street Journal suggests that continued delays indicate President-elect Donald Trump will not get to fly in the new Boeing 747s during his second term, with the latest projections targeting 2029 or later.

Trump is frustrated with the delays. Here's more from WSJ: 

Frustrated with the delays, Trump raised the project with Boeing CEO Kelly Ortberg when the two men spoke by phone in November. As he prepares to return to the White House, Trump has repeatedly asked advisers about the status of Boeing's work. Boeing used to be a great American company, he has told aides, according to people briefed on the discussions. What happened to them? Trump has asked.

In 2018, during President-elect Trump's first term, Boeing received a $3.9 billion contract to build two new 747-8 aircraft for use as Air Force One. The aircraft were supposed to be delivered by the end of this year.
