Are you suggesting that there are more airplanes in the air today than there were in the ‘60s or ‘70s?

I’m going to need to see charts, graphs and Congressional testimony to believe that one!

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.
