This is the story of US troops who think they saw Bigfoot in Vietnam
In the Kontum Province of Vietnam, near the borders with Laos and Cambodia, there were many reports from U.S. troops on patrols of a strange, not-quite-human but not-quite-ape creature the locals call Nguoi Rung, or "The people of the Forest." In other words: Bigfoot.
Gary Linderer was on a six-man patrol with the 101st Airborne's Long Range Reconnaissance Patrols. While struggle through the underbrush, he ran into "deep set eyes on a prominent brow... five feet tall, with long muscular arms." The creature "walked upright with broad shoulders and a heavy torso." His battle buddies told him he just saw a rock ape, but Linderer had seen Rock Apes before. This was no Rock Ape.
Like the Yeti in the Himalayas, and the Sasquatch sightings all over North America, the Nguoi Rung is a oft-told tale in the area, but despite endless the sightings and folklore attached to the semi-mythical creature, no concrete evidence exists. Linderer wasn't the only witness, either. Army Sgt. Thomas Jenkins reported his platoon was attacked by these apes throwing stones.
Toward the end of the war, Viet Cong and NVA soldiers reported so many sightings of the reddish-brown hair-covered Nguoi Rung the North Vietnamese communist party secretariat ordered scientists to investigate.
Dr. Vo Quy, a respected ornithologist and environmental researcher from Hanoi, discovered a Nguoi Rung footprint on the forest floor and made a cast of it. The cast was wider than a human foot and too big for an ape.
In 1982, another Vietnamese scientist, Tran Hong Viet discovered more footprints, which led zoologist John MacKinnon to investigate the region. MacKinnon called the area a "tiny, pristine corner of the world unknown to modern science."
In 1969, MacKinnon discovered manlike footprints in Borneo's jungles, which the locals called Batatut. While much of the evidence surrounding the existence of these apes is anecdotal, MacKinnon, known for his discovery of new mammal species in Vietnam, believes there is a possibility the existence of a previously unknown ape species is real.
The account of Nguoi Rung meeting American GIs in Vietnam was first published in Kregg P.J. Jorgenson's Very Crazy, GI: Strange But True Stories of the Vietnam War.
