I've been trying to come up with some numbers that will impress upon
my son the stark rarity and unique nature of his accomplishment as a
new Private Pilot.

In short, I thought it would be neat to figure out how many pilots
have EVER flown, since 1903. It's easy to get the number of US pilots
year-by-year, but (of course) these include duplicates over time.
Therefore, I'm stumped.

Any ideas how to tabulate this figure?


Don't you have guests to look after?
