Drone op (sort of, not dedicated but have for years as a camera op) here. It’s difficult! You really have to get your bearings on the way up looking towards the horizon and then add up context clues based on the shifting scale as you move, kind of taking each object in relative to each other.

Lol kidding. We have a spotter 99% of the time. You’re in goggles or watching a monitor, they’re going “Stop. Left. Turn 40 degrees. Drop a few inches slowly. Stop.” etc.
