The CH-46 Sea Knight and its Canadian variant, the CH-113 Labrador, can land on water and rest for up to two hours in calm water. The rear sponsons hold two of the three landing gear units as well as self-sealing fuel tanks. The helicopter began service with the United States Marine Corps in 1962, and with the Canadian military in 1963, and is used to carry cargo and combat troops.

Chinook Jargon in British Columbia by gold prospectors and Royal Engineers. As industry developed, Chinook Jargon was often used by cannery workers and hop pickers of diverse ethnic background. Loggers, fishermen and ranchers incorporated it in their jargon. A heavily creolized form of Chinook Jargon (Chinuk Wawa) is still spoken as a first language by some residents of Oregon, much as the Métis language Michif is spoken in Canada. Hence, Chinuk Wawa as it is known in Oregon is now a creole language, distinct from the widespread and widely varied pronunciation of the Chinook Jargon as it spread beyond the Chinookan homeland.
