A high-tech uncrewed Ocean Infinity ASV equipped with a NORBIT WINGHEAD multibeam sonar and cameras is attempting to solve the mystery of a 1968 plane crash that killed three people during a scientific mission in Western Lake Superior.

For decades, seat cushions and pieces of metal have washed ashore, but the wreckage of the Beechcraft Queen Air and the remains of the three men have never been found in waters reaching depths of 400 feet (122 meters).

On Monday, an autonomous vessel called the Armada 8 was deployed in Lake Superior. The ASV was accompanied by boats and crew from Michigan Tech University’s Great Lakes Research Center in Houghton, located in Michigan’s Upper Peninsula, and with NORBIT personnel supporting the operations remotely.
