Trivia

 * The "Katzenelenbogan" is most likely spelled with one 'L" because the creators of the airport must've taken reference from the monument (which had also spelled Jacob's last name wrong) and thus, "Katzenelenbogan".
 * According to the map of Elwood City and Crown City, the airport location could be a reference to Montréal–Pierre Elliott Trudeau International Airport.
 * Based on its' name, the airport could also be based on Logan International Airport in Boston.
