how many people flying at any one time?

If you want general aviation numbers, it should be easy to compute.
GAMA (www.generaviation.org) publishes stats on #'s and annual hours
of active aircraft. NTSB accident data (www.ntsb.gov) can be used to
derive the average # of occupants per aircraft, and by time of day if
needed.

Do you report your annual hours flown to the government (or GAMA, for that
matter)?

Doesn't matter. For one thing, the number of people in the air in GA
aircraft at any one time
are going to be insignificant compared to the number of people in
commercial aircraft, and
the latter number is going to be fairly easy to estimate. (This data is
probably available
somewhere, but you can always take the know number of flights each day,
assume an
average capacity and load factor, and come up with a reasonable
estimate.) If you want
GA numbers, you can get an upper bound by checking the registry to see
how many
aircraft are listed and what types, determine how many seats this
translates into, and
assume everyone is full and in the air at the same time. You know the
actual number has
to be much less that this, so now you start making assumptions and
approximations.

Isn't that on the medical application? It's also reported to
insurance companies; FAA and GAMA publish their analyses of activity
from the data. What's the problem?

Bob, reliable estimates of such things don't necessarily require exhaustive
counts. Carefully designed sampling works, too.

It would be interesting to figure out how many people have flown, in total.
I just saw a figure that said the Boeing 747 has safely flown an amazing
number of people (half a billion?) over the years.

An easier one to determine would be how many certificated pilots there have
been since 1903. We always bandy about stats like "only .05% of the world
can fly" -- but does anyone really know that figure?

Just about 67% of all statistics are made up out of thin air.

No, 67.8%,

Thats not the question he is asking - he wants to know how many people
are in the air at any one time and without qualifications as to GA or
otherwise.

I would probably guess that there is a couple of million in the air at
any one time and ten times that in terminals seeing them off and
arrive

So, your guesstimate is that for every one person flying there is a
cummaltive 10 people in a terminal watching them depart or arrive. That, to
me, seems like an inflated estimate.
