McDonnell Douglas F-4 Phantom

The F-4 was used extensively during the Vietnam War, first as the principal air superiority fighter for the U.S. Air Force, Navy, and Marine Corps, and later as a ground-attack and aerial reconnaissance aircraft.
Reputation
Imitating the spelling of the aircraft's name, McDonnell issued a series of patches. Pilots became "Phantom Phlyers", backseaters became "Phantom Pherrets", fans of the F-4 "Phantom Phanatics", and call it the "Phabulous Phantom". Ground crewmen who worked on the aircraft are known as "Phantom Phixers".
The military stopped using the F-4 Phantom in 1996, when the aircraft was officially retired from active service.
