Difficult to find numbers, as I probably am not using the right search terms Here’s an interesting chart for passenger kms worldwide.

Hard to read for the earlier years, but something like 5B in 1965 and 10B in 1975.

180B+ last year.

So, yeah, I guess that would qualify as “more planes in the air.”

Here’s another graph, I think it’s for US flights only per year. 1965: about 2M. 1975: about 8M. 2008?: 20M.

I think most people forget how unusual air travel was back then. Today it’s utterly routine.

Happy to see other numbers if you have them.

I have to apologize to you as I didn’t mean for you to take the question seriously. However, your work does make the point both you and I were trying to make.

Thank you for your efforts.
