Bjork Tandem Monoplane
Constructed in September 1910 by Edward Bjork, a Chicago building contractor residing at 934 Fletcher Street. His machine was forty feet in length by twenty in width. He constructed it in a shed at Evanston Avenue and Byron Place.
Bjork was a member of the Swedish-American Aerial Club of Chicago – a manufacturer of aerial machines that failed to conduct the business for which it was created.
