TWA 727-231 "Ramjet".

Shown here parked on the gate in St. Louis at night. It was painted, obviously, for St. Louis's recently aquired football team. The aircraft was known to TWA crews by several nicknames, including "Ramjet" and "Helmut Head". With the retirement of the 727 TWA painted another such helmut on a 757.
