I brought this point up online over 20 years ago. The pushback I got was it was too expensive to set up such cameras. I countered with if a 7-11 could install a security camera that recorded on VHS tapes, a couple cameras could be mounted in the control tower pointed at the runway. I still got a lot of pushback.

Frankly, I'm baffled.

So why do you think such cameras don't exist?

P.S. Back then, as well as today, I'm surprised at the level of pushback on this question, but no answers.
