content: Rayo's Number, WTF am I supposed to do with that? Just the number of digits in that number can create a black hole just trying to guess what that number may be.There are even larger infinities than just good old plain infinity.

content: Quote from: BrianHG on January 17, 2023, 09:30:10 amYeah. I mean, when you think that >11,000 units of the 737 family alone have been made (and another 4000 to be delivered), and that there are nearly 3000 of themin the air at any given moment. (And I assume it’s similar for the A320 series.)

In the US, there are very few 737 Classics or earlier still flying. Still, the number is probably not too far off if one only counts commercial and military aircraft. For general aviation, add at least another 400,000 aircraft.

content: According to Statista there are just over 200,000 aircraft registered in the US. There were no comparable free statistics for the rest of the world, but I would guess the number is more than 200,000 but less than a million.Getting a slippery number like this within an order of magnitude is actually sort of impressive, and it appears they might have barely achieved that. Even closer if they are only counting the commercial fleet.
