If Aviation Pro is referring to the 747, he's lying and/or ignorant. Qatar gave the plane to the US Air Force, not to Trump personally. Given Boeing's performance on a contract first received from the OhBummer! MalAdministration, when Trump leaves the WH in January 2029, this plane will almost certainly be used by the next President.
IF this 747 is eventually retired and becomes an exhibit at the future Trump Presidential Library and DU-folk think this is a first, they are ignorant of the former AF1 and Marine 1 on permanent display in the Ronald Reagan Presidential Library Air Force One Pavilion. There's also an F-14 Tomcat on display outside.
Speaking of Presidential Libraries, in what decade is OhBummer!'s projected to open?
