A 77-year-old plane crash in Saskatchewan has only just been officially documented. Operation Attaché, a 1948 U.S. Navy Beechcraft Expediter flight, was a crash site that many were aware of, but its identity was not formally recorded after a major RCAF-led search -- the biggest search and rescue in Canada at the time -- found the five survivors of the Manitoba September 1948 crash from Churchill to The Pas. Documentarian Scott Woroniuk and historian David Riach join Evan to discuss the work that led to this journey and the documentation process for Lost in the Muskeg: The Plane Canada Forgot.
