A slight digression, but I remember clearly one of my early flying lessons, and the first time we had got above 5000'.
My instructor asked me: "Can you see the Winter Hill TV transmitter?"
I knew we were in the vicinity, but for the life of me I could not spot it. "No" I said.
"It's there right ahead" he assured me.
I looked hard. Still nothing. Then, suddenly I saw it. A landmark that had, for my entire lifetime, projected entirely above the horizon, was now suddenly entirely below the horizon, just 2 or 3 miles ahead, and as clear as anything once the perspective mental block had been removed.
I learned about flying from that.
