Two Ford Tri-motor flights – 75 years apart

In 1935 I was six years old, and we were living in Ponca City, Oklahoma. One day a Ford Tri-motor flew into our grass airfield and offered rides, at a price, to our “city’s” inhabitants. I was completely hooked on aviation from that moment on, and determined that I wanted to be part of it.
