Debris from a missing Ontario air ambulance that had been carrying six people, including four Canadians, has been spotted off the coast of the United States. The U.S. Coast Guard said search crews found a debris field roughly 150 kilometres southeast of Boston and confirmed it belonged to the missing aircraft. The search for the missing passengers remains ongoing. As Nathaniel Dove reports, the frantic search began after the Federal Aviation Administration lost contact with the plane early Saturday as it travelled from Bermuda to Boston.
