At the bottom of the page titled About the Noorduyn Norseman, the airworthy list has been recently updated and shows 16 active airworthy Norseman in the world today. While this number is down, there are many restorations ongoing and the warbird community of Norseman appears to be growing. The largest single customer for the Norseman was the United States Army Air Force during World War II accounting for approximately 83% of total production!
As a private owner/operator the type is rather expensive to fly and commercially a handful continue to shuttle between northern lakes. Keep ‘em flying!
