What happened
On Wednesday, June 24, 2026, Air Canada Express flight AC7664, marketed by Air Canada but operated by regional partner PAL Airlines, experienced an emergency diversion. The De Havilland Canada Dash 8-400 departed Newark (EWR) for Halifax (YHZ) at 12:54 PM local time. Approximately 30 minutes into the flight at 23,000 feet, the captain became incapacitated due to a seizure. The first officer managed the emergency, diverting to Boston (BOS) and landing at 1:56 PM local time. The captain was removed from the cockpit and transported to a hospital. The incident is cited as a key example of the importance of two-pilot crews, particularly as the industry discusses single-pilot operations
