What is the max number of planes that have been in the air at one time worldwide?
Answers:
I doubt that anyone will know that.
Commercial flights - possibly, but there will be hundreds of military ones (top secret), plus private ones e.g. pleasure rides for 20 minute fly-by's, and heaven knows how many remote control ones. (Some of these will be military as well - especially in Isreal)

I don't think that any one knows the right answer.I even don't know if anyone knows the number of airports in the world
I don't think you could find the answer, but as 4 the number of airports tis there in wikipedia.
Damn near impossible to tell. Might try asking any ATC controllers (if there are any) here, but the response might be: "More than I care to know."
Too many. But I don't fancy standing in a field counting every single plane which flies over my head. plus I'd look like a lunatic.
