Both VC-25’s went into service in 1989......shade under 20 years old but very low flight time and meticulously cared for.

DC3 airframes were shown to be sound after 50 years.

My brother, who is now an AF colonel, has been in military airlift his entire career. He has yet to fly a plane that is not older than he is. 20 years old is pretty young in the Air Force.
