Article has several links to HD quality underwater WWII crash site video & photos along with current unmanned and diver-held search technology. The state of preservation of the crash landed Corsair skin is incredible, the downed Avenger not so much (spun in with a wing shot off).

Ric I wonder if the Navigator diver-held sonar would assist on the next expedition reef search as seen in the Go-Pro video link. The University of Delaware was involved in this project as well.
Ran across this on the NOAA site today. Hope the Electra looks this good.
