"A General Motors/Eastern Aircraft Division FM-2 "Wildcat" was pulled out of Lake Michigan on Dec. 7, 2012 after spending 68 years beneath the waves."
Yes, the Navy had two fresh water aircraft carriers during WWII -- in fact, they were sidepaddle steamers!
The USS Sable (IX-81) and...
... her sister ship on Lake Michigan, the USS Wolverine (IX-84).
Shame we don't have any carriers in the Great Lakes any more -- never know when Canada, or Wisconsin, might get uppity.
