Now, that's really handy to know.  I'm planning a flight from Chino to
Sedonna and it works out to be 0.01362 equators.  I can do that in about
1.25 hours so that should make my speed... say about 0.010893 equators/hour.
Now we're cookin' with gas.  I suppose it would be easier and more
meaningful to relate this as 10.9 meq/hr  (meq - mili equators).

Now if someone would hand me a calculator I need to compute the weight and
balance... Let's see, the gross weight is 8.09587 x10^-7 z smu.  (z smu =
zepto solar-mass-units).  Even with my wife's extra bag I should be under
that.  :)
