Nice write up, Fred.
Nits: dividing by the speed of light works better than multiplying.
And, I _think_ (the flesh sags, the hair falls out, the memory fails...)
that the geosynchronous orbit is 22,300 miles. But who's counting?
Key thing is that we're going to see many more satellite transport options
over the next 3-5 years. And, there will surely be selected situations for
which one or more SATCOM alternatives will solve problems that purely
terrestrial means won't be able to solve. Stay tuned. YMMV.
