This will be great news to the family’s of the men who were never found. From Bloomberg News:

Canadian divers may have found the wreckage of a U.S. Army amphibious plane that crashed in the St. Lawrence River in eastern Quebec in 1942, the Associated Press reported, citing Parks Canada officials.

Parks Canada divers found the wreck while doing routine work near the village of Longue-Pointe-de-Mingan, according to the report. The wreck hasn’t been confirmed yet as the lost U.S. plane, which crashed carrying a crew of nine in rough weather on Nov. 2, 1942, in the Gulf of Saint Lawrence, the AP said.

Four crew members of the Maine-based PBY-5A Catalina survived the crash, while five others died inside the aircraft, and their bodies were never recovered, the AP said. Sonar data indicates the seaplane is in good condition and human remains may be found, according to the report.

The find is “tremendously important” because of the history of cooperation between the U.S. and Canada, Joe Breen, the defense attache to the U.S. Embassy in Canada, told the AP.
