Shot on Oahu as Vietnam during the Vietnam War. We took over a banana plantation and cleared the top of the mountain to build a military camp. I found Army Corp of Engineer manuals and we built the buildings as laid out in the manuals with the same materials. We built supply stations, a mess hall, the sleeping quarters, officer’s quarters and offices, a recreation hall, a chopper landing pad, guard towers, latrines, etc. Used miles and miles of sand bags. Initially conceived as a pilot and series the show was made into a TV movie.
