hm_save_cache

Filename is <code>"route_star_cache_id_XXX.rda"</code> where "id" is the id
parameter and XXX is made up from the name of the grid (which identifies the
map used) and the 'aircraftSet' attribute of the aircraft dataset (which
identifies the source). This is because the cache should be for a unique
combination of these (and you must have these available, because they were
needed to generate the routes).

For supersonic aircraft, flying subsonic over land,
find the best route between airports. Allow for coastal buffer and
potentially closed regions. Use a minimal model of aircraft
performance: the focus is on time saved versus subsonic flight, rather
than on vertical flight profile. For modelling and forecasting, not for planning your
flight!
