Bob,
Checked my records and it was Hotel 9 also a place called Mike 6. Both were in Indian Country. We flew both areas in 66/67 working for ????? out of FOB 2 Kontum, FOB stood for Fly Over Border. Lots of AAA and fast movers supporting on some extractions. I know I remember on one occasion hearing that funny buzz on the radios, we were already at tree top level flying contour.
