the old mantra from firefighters "risk a alot to save alot, risk a little to save a little" comes to mind when I hear of medevac accidents.
Lives are important, but at what cost?
not everyone can be saved, and you don't line up your highly trained resources, such as pilots, paramedics, or firefighters etc like lemmings and let them keep them heading into impending death one after the other. But we see this scenario play over and over with medevacs.
Heaven forbid we put crews lives on the line to attempt to save someone who isn't knocking on deaths door themselves.
