A Personal Anecdote from the Developer
Back in 1964, while I served as Minister of Music and Education for Pleasant Ridge Baptist Church, our Sunday School materials were delayed in shipment. I volunteered to accompany the pastor’s son, Charlie Dollar, in a Cessna 172 flight to Nashville to pick up the supplies. On the return leg, the aircraft began to backfire severely. We attempted to contact KMWA’s tower but received no initial response.
Switching to the emergency frequency on 121.5 connected us with KCGI, who then informed us that KMWA’s tower radio had been disabled by a lightning strike and suggested using their ground channel. Upon touchdown, we allowed the engine to cool fully, and following a successful test run, we took off again. The mechanics on site had some reservations, but I assured them of my familiarity with field landings.
We eventually arrived at Greenville, Illinois, where a mechanic greeted us in a rather heated manner. He hopped into the cockpit to verify the plane’s condition and nearly lost control upon takeoff. After landing with a somewhat pale expression, he decided to ferry the aircraft back to St. Louis and reevaluate his recent overhaul work.
