The White House is working to quickly upgrade the Qatari-donated jet that has newly started serving as Air Force One, a development that comes after administration officials internally discussed the need for President Donald Trump to avoid flying it in high-threat areas, according to two sources familiar with the matter.

Trump recently had to switch to the old Air Force One jet while flying out of Turkey amid purported concerns about the new plane’s missile defense capabilities.

Trump’s answer to a reporter confirms that the plane he got from Qatar still has lots of security issues.
