My first airplane flight was a trip my brother and I made from St. Louis to Indianapolis Indiana on Ozark Airlines. Ozard covered about a dozen Midwest cities. I was about 13 and my brother was about 16. Why our mother let us do that I have no idea. We stayed at a hotel in downtown Indianapolis and did the tourist thing for one day. We flew home the next day.
The plane looked a lot like this one, a DC-3. You walked out onto the tarmac and up the rollaway stairs and boarded at the rear door (the only door) and had to walk UP the aisle to find your seat on the prop aircraft. There was no TSA and/or baggage inspection in those days. That trip fueled my love for air travel.
Ozark Airlines had a special one summer where you could fly anywhere they served over the weekend for $30. A friend and I charted out a trip starting on a Friday and had about a dozen stops until we returned on Sunday evening. We spent one night in Minneapolis and I can’t remember where we spent ther other night. I think I was about 15 or 16 then. I still love the travel by air even though it is a lot more trouble to do so.
