The Legend of Dust Off, America's Battlefield Angels. Viet Nam may be the only war we ever fought in which the American soldier enhanced their heroism with humanitarianism unmatched in warfare. Humanitarianism was America's great victory in Viet Nam. Spearheading the humanitarian effort was Dust Off, the most dangerous of all aviation activities and the most amazing battlefield life saver in the history of warfare. This is the story of the father of Dust Off, Charles Kelly, who died to save Dust Off. His dying words, "When I have your wounded," set the standard for aero medical evacuation to this day. It is also the story of Kelly's disciples who struggled and died to meet his standard. One unit, the 54th, did. The author, Gen. Brady, learned from Kelly and led the 54th as it rescued over 21,000 wounded-enemy and friendly-in 10 months; while sustaining 26 Purple Hearts. It is also the story of faith in combat and the miracles it produces. 39 photos.
