They started the globe scam in the 1930s with the logo from Universal Studios by showing a biplane circling their fake, satanic globe. Imagery works on the mind, repeatedly. No words, just that image for decades. Especially the very young.

Then, in 1965, they made damn sure a globe was in every classroom.
"Man in Space", under Kennedy, was the big CIA//NASA psyop of stop animation of capsules in space. Question, all those space walks I saw as a child on TV in the 60s...who was filming them? When I asked the question, you got called an idiot. But no one had an answer.
Then, in 1977, they taught flat earth as a mindless idiot myth.
