NOAA in the Great Lakes supports inter-agency search for WWII aircraft
Did you know that there are about 120 World War II era aircraft lying at the bottom of Lake Michigan? The Navy used these aircraft to train and certify pilots to take off and land from aircraft carriers during World War II. U.S. Naval operations along Lake Michigan, one of the Great Lakes, began in 1923. Between 1923 and 1942, operations expanded as the Navy built hangars, airfields, and landing strips across the village of Glenview, Illinois.
By 1942, the Navy had a robust presence on the shores of Lake Michigan. With the U.S. entrance into World War II, the Navy needed a location to train carrier pilots. The growing threat of enemy vessels and mines along the Pacific and Atlantic coastlines and an already strong Naval presence in the area made Lake Michigan the safest location for carrier training. more here
