Back in the early 60s, I used to sit in my parents pasture and watch planes from Eglin. Most of them were military jets but there were regular flights of DC-3s. They were flying from Eglin to Atlanta or the opposite.
Southern Airlines had a terminal on Eglin. I never went inside but it was an old WWII era wooden building. Next to it was a snack shop, also in one of those old buildings.
Used to see a Chalk’s airline DC-3 fly over the neighborhood every afternoon around 4:15 on the Miami to Key West run back in the mid 70’s.
My first flight was on an Ozark DC3 from Peoria to St Louis. Since then several flights in Indonesia.
