St. Pete-Clearwater International Airport

On PI day, we notice PIE Airport

No word if they’re handing out free Key Lime pie today at Florida’s St. Pete-Clearwater International Airport, as they have in some past years. But we celebrate that airport today anyway, because it’s PI day and the airport’s identifier code is PIE.

PI Day celebrates the Greek letter “π” (Pi). That’s the symbol that represents the mathematical constant that is the ratio of the circumference of a circle to its diameter and has been calculated to over a trillion digits, the first of which are 3.14.

As far as we know, PIE airport didn’t get that code because everyone there loved eating pie. Instead, it is because when it was orignally constructed, in 1941 as a military flight-training base, its name was Pinellas Army Airfield.

If you stop by PIE airport today, be sure to take a look at some of their public art, including this piece by Mary Klein called Mile Markers.

How are you celebrating PI day? In my neighborhood, there’s a pizza restaurant selling pies for $3.14.
