My Brother-in-Law was flying Neptunes during that time. They would fly right over the Soviet ships taking photos, I think he said about 20 feet over their highest part. He said some would throw stuff at them and some would wave.
My other Sister was working as a clek/typist at Hurlburt Field. There were Cubans everywhere and bunches of B-26’s, each one with 8 fifty calibers in the nose. Of course they were not very effective against Cuban/Russian MIG or whatever they were, jets.
Difference was, at the time we were pretty sure the government was on OUR side . . . .
