A few years ago I was looking through an almanac and found a table of
airline distances between world cities.  The longest distance listed was
Bangkok to Lima, Peru, which was a bit over 12000 sm (i.e. nearly half
of the earth's circumference).  I got out my globe, placed an index finger
on each of the said cities, and the sphere was balanced.  Are there any
other "antipode pairs" of major cities?  And how plausible would airline
service between them be?
