I have heard of many people speculating about this, and have seen talk about this on a couple threads here.
The rumor is true that a FG-1D Corsair did crash into Lake Nimisila. It did so after the landing gear did not extend fully and the pilot could not land at Akron-Fulton Airport. The pilot jumped from the plane at about 7,000 feet and was fine (just minor bumps and bruises), and he saw the plane crash and "explode" into the lake.
Now, as for if the Corsair is still down there, Goodyear did recover it. There may be small parts left in the lake, but for the most part Goodyear recovered it. And the pics of the recovered plane are below.
(MAPS just received a ton of documents from Goodyear Aircraft that had been in the posession of Lockheed Martin sine they now own the ex-Goodyear Facilities at Akron-Fulton Airport. In them I found a ton of great things, and among them, I found the official reports, as well as pilot and witness testimonies from this crash.)
