Why evacuating wounded troops by air might do more harm than good

Over the last 15 years, the United States has flown its wounded troops out of combat zones to hospitals around the globe. The logic: get those hurt in places where medical supplies are limited to places where they are not. The fastest way to do this? By air.

Yet according to a new, first-of-its-kind study conducted by the University of Maryland School of Medicine, rapid air evacuation has the potential to cause more damage to those patients suffering from an extremely prevalent battlefield affliction–traumatic brain injury.
