It is not common sense by the average citizen that there are injured people that are not good to go by the big commercial planes. As these case patients do not want to be onboard public airliners . This is because these case patients are not in a non life or death circumstance , jet ambulance crews are mandatory. Those few people are dependent on a nurse ; and accordingly they can not go on the public charter air charter services. Elderly men and women who are in need of a medical technician are helped by medical air evacuation businesses. Emergency medivac outfits generally can be discovered by patients with the help of the many internet resource directories available.
