And in how many of those other countries do the same SAR operators cover all of the country?
Many countries have specialised mountain SAR and many have just maritime SAR, many countries have dedicated Air Ambulance/HEMS for inland work but not dedicated SAR assets who also do everything else.
Strange that the US coastguard liked to send their pilots to us (RN and RAF) on exchange - to a man they went away far better SAR pilots for the experience.
