I wonder how many of us who were pilots could have learned to fly had we been taught in another language and had to learn mostly by observation.
Most of the vietnamese pilots that I knew in Nam were prety good if they survived a few hundred hours (sort of like us).
The ones who flew the the H-34s out of Kontum, the "King Bees", were damned good. And from what I saw and heard,"Cowboy" and "Moustachio", Vietnamese plots who flew the SOG and FOB missions, were as good as any American pilot I ever met. And as brave.
sorry guys. just my opinion.
