Everything in HAA revolves around Medicine, not Aviation, Capisce? If the Medical industry--the Hospitals and the EMS organizations--don't call, you don't haul, and you'll be out of business in short order.
The idea that "without us you'd be nothing" is the wrong mindset, and leads to a lot of problems in HAA. HAA IS about aviation and it IS about medicine.
See the fact is, the Medicals are your aviation customer.
This idea is also wrong, and just a little dangerous. Regarding pilots, mechs, and med crews - none of them works FOR the other, they work WITH each other. If someone is telling you that your medical crew is your customer, then you have a situation where the medical side has de-facto operational control of the pilots. The problems created by that is why the question of operational control receives so much attention.
In HAA, the customer is the hospital (if your program is affiliated with one), and the hospitals and first responders who call you. Without THEM (the people who call), the pilots, mechs, and med crews will be out of a job.
what is really going on behind these stories is that the Pilot or Mechanic in question has the People skills of a Matador and the emotional intelligence of a drunken blacksmith, and can't master the critical Skill of Smilin'-and-Noddin' until he can call the Boss and get things straightened out...
In aviation and medicine you're going to find people who are a bit head strong and a little too "type A" in the wrong kind of way. Sometimes it's a pilot who has trouble working well with others, and sometimes its a nurse or medic. There's plenty of good and bad to go around. It requires good leadership on the part of those in the chains of command on bothe the medical and aviation sides. Why does HAA have many of the problems it does? Lack of leadership.
