Air ambulance service - anyone know anything about these guys?

Anyone have any experience with Aero Care?

A description of what the service is taken from their website:

AeroCare Air Ambulance Service offers 24 hour emergency and non-emergency ambulance services throughout the world. Our philosophy is to provide out patients with the highest level of aero medical care including medivac services at the most cost effective price. This commitment to quality and cost effectiveness is delivered by combining the talents of our highly trained medical flight crews, our safety and service oriented Flight Crews, and a quality driven management team dedicated to treating each of our patients as if they were members of our own family.

Their FAQ says that many insurance plans cover them, and they look to me like a good idea for caregivers traveling with their care recipients to know about since their FAQ states:

What type of patients' require an air ambulance?

Patients that need to be transported distances over 200 miles and require medical attention and/or are unable to tolerate sitting upright in an airliner. AeroCare typically transports patients injured while on vacation needing to be flown home, patients with serious medical conditions needing transportation to a distant medical center that has capabilities unavailable locally, chronically ill patients who want to relocate closer to family members, and patients who are travelling outside the US and become ill or injured requiring evacuation back to the states.

So if anyone has any experience with these guys, please, let us know what you thought of their service and if you would recommend it to other family caregivers.
