One quirk of living in Hawaii is that it’s not unusual for people to have to fly for medical treatment. There aren’t a lot of specialists on the Big Island. Typically, they’ll visit once or twice a month. But the bigger issue is that expensive pieces of medical equipment are mostly on Oahu. Need an MRI? You might have to go to Honolulu.
For scheduled appointments, people generally take commercial flights, but some conditions, and most medical emergencies, require a medivac flight.
Upolu Airport, which is basically a runway with few facilities, is used by these medivac aircraft on a regular, if not frequent basis. These photos are of one such plane awaiting a patient, then heading down the runway and into the air, bound for Honolulu.
