It is very possible, as Otis is not far from Hyannis at all!
We were at a “Thunderbirds” air show at Otis. Word began to circulate that JFK was coming in. We hung out long after the show was over, and sure enough, AirForceOne landed and then taxied towards us. I can still picture the American flag on the tail visible above a row of trees as it moved towards us. Then there he was, (I distinctly remember red hair, redder than I’d ever noticed in any photo). He was carrying a hat. He was known for not wearing hats, but it was a gift he had just received from a foreign dignitary. Best I can recollect it was a sudden, emergency visit cause Rose was sick. Do you happen to recall an Air Show just about the day you took that photo?
