In Maine, the family of Marine aviator Ben Cross has come forward to identify him as one of three who could not be rescued.
First Lt. Benjamin Robert Cross, 26, was said to love flying.
An investigation has been launched into the cause of the tragic crash.
"He would sacrifice himself in a minute to make sure that his fellow service members were safe", Cross said.
The statement said a diving team arrived on scene and "would conduct remotely operated underwater vehicle operations", at the site of the crash. Of the 26 who were aboard, 23 were rescued.
