This was not uncommon during cross country trips in the US during and right after WW2. Many were not planned as a formal stop such as an airshow, exhibit or planned war bomb tour. Most were simply going from one base to the next with an unplanned stop in between. Dad did this a couple of times right after the war to our hometown, once in a Hellcat and another time in a Corsair. Much easier back then to pull off a slight deviation as it would be today to try to "deviate" away from a scheduled flight plan.
I recall as a kid in my hometown in Northern Michigan hearing the noise of the old converted (fire bombers) Avenger torpedo bombers that would stop at the local airport for fuel unannounced. Super excited to ride my bike as fast as I could to get to the airport to just hang out until they were fueled and then watched them take off. Usually about 5 or 6 of them. No airshow, no announced gathering, just a surprise stopover for fuel. Those were the good ole days in the late 60's early 70's if I recall.
A crowd gathers at Blue Grass Field, Lexington, KY on July 11, 1942, to watch the first airplane land on the paved runway of the new airport. B-25 was being flown from Meridian, Miss., to Wright Field in Dayton, Ohio.
