This storm is almost mythical for hunters now. Due to an Indian summer there were almost no ducks in the upper Midwest prior to this storm and it pushed ALL the migration down. Those that made it talk about it being the best hunting day of their life, yet many died.
It's important to also remember they didn't have advanced weather notice, cell phones, goretex or even reliable outboard motors. It was truly the "perfect storm" of duck hunting.
I think someone should make a movie about it, it would be a hell of alot better than the 5 version of whatever franchise or remake.
Here's a good write-up on it from the NWS.

"Historical Background
Weather observations, forecasts and warnings were much different in 1940 and so were the ways people received information. Until 1934 the Weather Bureau offices operated 12-15 hours a day with two basic observations taken at 8 a.m. and 8 p.m. The observations were transmitted via telegraph. There were no satellite images and few upper air observations. In the Midwest the Chicago District issued weather forecasts for Illinois, Indiana, Iowa, Michigan, Wisconsin, Minnesota, North Dakota, and South Dakota. Weather Bureau forecasts, which were issued mid morning and mid evening, were brief and general. Distribution methods ranged from reports in newspapers, on cards displayed in the lobbies of public buildings, radio broadcasts, or by telegraph. "
Then...
"Hunters taking advantage of the holiday and extremely mild weather were rewarded with an overabundance of waterfowl. Many would later comment that they had never seen so many birds, but the birds knew something most of the hunters didn’t. They were getting out of the way of an approaching storm.
Across the Midwest hundreds of duck hunters, not dressed for the cold, were overtaken by the storm. Winds came suddenly then masses of ducks arrived flying low to the ground. Hunters, awed by the site of unending flocks of birds, failed to recognize the impending weather signs that a change was in process. Rain started and temperatures fell rapidly. By the time the rain, sleet, then heavy snow reduced the visibility to zero, hunters lost their opportunities to return safely to shore. Hundreds of duck hunters lost boats, gear and guns as 15 foot swells and 70 -80 mph winds swept down channels and marshy backwaters. Some hunters drowned, others froze to death when the near 60 degree temperatures plummeted, first to freezing, then into the single digits."
