Oh thanks that makes sense! Those "flying doctors" already exists in Australia and one of them saved my life 13 years ago : landed on a single lane road on the middle of the desert to pick me and my friend in a thought condition after a car crash. We arrived in the hospital 2 hours later, instead of 12 hours car drive. IIRC it was a small propeller plane looking simple and not so new or fancy. Didn’t remember the flight :( they quickly nailed me to dream after landing.
