Peru have been in the Upper Huallaga Valley. The coca is flown to Colombia, where it is used to create cocaine, which is subsequently shipped to the United States. Vladimiro Montesinos, ex-head of Peru's intelligence service, is reported to have received $50,000 for every plane laden with drugs allowed to leave the Huallaga Valley. On 27 August 1994, a Drug Enforcement Agency CASA 212 Aviocar light transport aircraft (reg. N119CA) crashed into a mountain (or at the end of a box canyon) north of Puerto Pizana, San Martín, Peru. The crash reportedly happened while on a flight from Santa Lucia to Pucallpa, in the Huallaga River Valley region, and apparently owed to bad weather and low visibility (rainy and foggy) conditions during a counter-narcotics reconnaissance operation. The plane's five occupants, DEA Special Agents Frank S. Wallace, Jay W. Seale, Juan C. Vars, Meredith Thompson, and Frank Fernandez Jr., were killed. This accident precipitated the end of the US anti-drug Operation Snowcap, under which the ill-fated flight was taking place. Notable deaths Eric Fleming who played trail boss Gil Favor in the long-running Western TV series Rawhide drowned in the Huallaga River. During the shooting of location shots for an MGM film titled High Jungle on the Huallaga River on September 28, 1966, Fleming fell from a capsized dug-out canoe after paddling it beyond the rapids. His body was lost in the turbulent water and was not recovered until three days later.
