Did you spot the error in my math, deliberately made to test you?  :)

No?  Well Steve did. Hard to believe I actually used a calculator and 
STILL got that multiplication wrong.  Thanks, Steve!

   The correct calculations are:

   MCD = 2 * 6371 * arccos [ 6371 / (6371 + 1460) ]
       = 12742 * arccos [ 6371 / 7831 ]
       = 12742 * arccos [ 0.8135614864 ]
       = 12742 * 0.620545318575
       = 7,906.98 Km (4913.16 miles)
