WHY? Because they learned they couldn't afford it, and had to shut it down because it wasn't viable.
Which is why, also, many reverted to an alternate deliver model, where they somehow keep their NAME on the aircraft (pretenting to the public they actually operate such) while not even paying for any of it.
Even the hospitals who "operate at a loss" aren't really doing that, because they OVERBILL the patient downstream for asprin to make up for the cost of the helicopter in their operating budgets.
So, Mr Z man is totally LOST in his understnding of the issue he is presenting!
