TORONTO, CANADA—The Province reports that an Avro Arrow test model has been found at the bottom of Lake Ontario by a recovery group. As many as nine of the free-flight, one-eighth scale model planes are thought to rest in the lake. Now covered in zebra mussels, the plane was reportedly part of a secret program to develop a supersonic combat jet, which was abandoned by the Canadian government in 1959. The actual planes in the classified program are said to have been destroyed. Once the model has been brought to the surface, it will be stabilized and displayed at either the Canada Aviation Space Museum in Ottawa or the National Air Force Museum in Trenton. The recovery group will continue to search for the other test models. To read in-depth about underwater discoveries in the Great Lakes, go to “Shipwreck Alley.”
