An article in the October 1972 edition of "Private Pilot" magazine featured Burkett's experience doing the show. The magazine's cover has a picture of what the plane looked like when it wasn't "in costume". The character of 5 O'Clock Charlie returns in the Season 3 episode "There Is Nothing Like a Nurse", in which the nursing staff is evacuated based on intelligence that points to an upcoming air raid on the 4077. In the end, the "air raid" turns out to be 5 O'Clock Charlie, this time armed with propaganda leaflets. During the U.S. Pacific campaign of World War II—specifically, during the Guadalcanal campaign (1942–1943)—Japanese bombers would harass various U.S. Army Air Force bases at night to deprive personnel of sleep. American troops nicknamed these bombers with various related nicknames, such as "5 O'Clock Charlie", "Bed-Check Charlie" or "Washing-Machine Charlie". Various methods of harassment included overflights at full throttle with propellers at near-flat pitch, or deliberately unsynchronized engines. One Washing-Machine Charlie appeared in the U.S. television comedy series "McHale's Navy". Washing Machine Charlie was also discussed in Gregory Boyington's autobiography and made appearances in "Black Sheep Squadron", the television show loosely based on Boyington's World War II exploits.
