These movies taken in the late 1930s and early 1940s in Northern Canada and Winnipeg, using an early Kodak 8 MM camera.
The Winnipeg movies were taken by Konnie Johannesson. The northern movies were taken by Konnie's brother-in-law Dr. James Morrow, at that time the resident doctor in Fort Smith in northern Canada.
( November 2006 - Thanks to Rich for identifying some of the aircraft, correcting my guesses after all these years )
Abrams Explorer takeoff probably at the Chicago Air Show
