Think, tracksterman, think! Where would these numbers come from? Do you
think that general aviation pilots report their passenger loads to Big
Brother? There is a remote possibility that someone could add up the
passenger manifests of the airliners in flight at a particular time and
report the total to Big Brother, but at what cost? And for what benefit?

I think he means "How many aircraft are aloft at any one time"??

No, I mean 'how many people' - and it's a global figure I want rather
than a US one. Of course this would only ever be a (very!) approximate
number, but that's all I need - and it has been done before, because I
remember reading the figure a couple of years ago. Just having a
spectacular lack of success finding it online...
