To find out more info look for the YO-3A and other US Army propeller LO and quiet surveillance platforms. This actually predates Vietnam as the US Army tried to quiet WWII observation AC. Apparently the YO-3A and others were pretty advanced with NVG and NOGs and used the same as we use drones today; unseen and unheard overhead at night watching for bad guys.
