*Some federal appointees. The head of FAA under Trump was Stephen Dickson, who was an F-15 fighter pilot in the U.S. Air Force, then a pilot for 27 years at Delta Airlines before becoming Vice President of flight operations [1].

The current head under Biden is Billy Nolen, a former pilot who flew the Boeing 757 and 767 and worked as an airline executive for years before joining the FAA [2].

By credentials, these two are definitely qualified.
