Air travel today has lost much of its romance and sense of adventure. Yet when it comes to the destinations that travelers flock to for business or pleasure, an air of mystery still can be found over many three-letter codes which don’t seem to make any sense:
CAE
The airport in Columbia, South Carolina has a mysterious letter “e” as its third letter. Could it be a filler letter or is there an interesting story for the airport code of Columbia Metropolitan Airport? The small town of Cayce is due northwest of the airport, and might explain the code, but it’s not totally certain. This airport has the distinction for being the training grounds for Jimmy Doolittle’s B-25 flight crews, which would conduct a bombing raid over Tokyo in April of 1942. This raid helped to raise the morale of the USA, which was struggling initially in both the European and Pacific campaigns of World War II.
BNA
Today’s Nashville International Airport still retains the airport code of BNA, which honors World War I veteran and air transport advocate Colonel Harry S. Berry. He was Tennessee’s WPA Administrator. The WPA was one of Franklin D. Roosevelt’s alphabet soup programs that helped put people to back to work during the Great Depression, and was responsible for the building of Berry Field in 1937. So despite the name change to Nashville International Airport in 1988, the three-letter airport code remains to remind people of Berry Field NAshiville.
