The pilot has been identified as Robert Mansell, originally from England. News reports say that he was knocked unconscious in the crash, and passengers were unable to get him out of the aircraft before it sank.
Several news stories about the accident quoted a Divi Divi Air spokesman who called Mansell a "hero" saying, "All the passengers survived and he is the only one missing. If he wasn't a good pilot, he couldn't have ditched it so everyone could be saved."
Condolences to the family and friends of Captain Mansell.
