Certified air evac charters are discovered by customers with the assistance of the telephone book. As a matter of fact , air ambulance fleets are a neccessity because of the fact that these individuals cannot be sent by your usual air charter services .. because these individuals need a complete ICU/CCU setup. Every once in a while there are patients who need a flight doctor and/or a breathing machine – and consequently these are the patients that can not go on the the usual commercial airline establishments. Elderly people that are with a variety of different patient needs and/or are in need of being sent to a more proficient medical care center are flown by medical air evacuation charters. It is not common sense by the average citizen that there can be a situation with sick people that have need of medical services.
