Situations where a medic can reach a patient but then the patient needs to be transported by air lift for less than 15km seem rather rare outside combat situations. Maybe if you use it to transport the medic to the site first to have them stabilize and prepare the patient for transport and then do a second flight to pic the medic up again.























Well, that is about getting a medic to a patient and not transporting a patient. So a completely different usecase.
(And getting a quadcopter like in the OP reliable enough to make it suitable for anything other that emergency transport of a patient that might otherwise die would be challenging).
