TORONTO, CANADA — Off-Duty pilot becomes unlikely hero, safely lands Air Canada flight amidst mid-flight crisis.

In an extraordinary incident, the safe landing of an Air Canada commercial jet airliner was attributed to an off-duty pilot, who swiftly stepped in after one of the on-duty pilots was rendered incapacitated mid-flight. The incident unfolded on Friday during a domestic flight stretching 1,300 miles (2,115 kilometers) from Toronto to St John's in the Atlantic province of Newfoundland and Labrador, according to an official disclosure by the Transportation Safety Board (TSB).

The TSB detailed in a released email statement that the first officer succumbed to incapacitation during the journey. At this critical juncture, a deadheading captain, essentially a pilot traveling for a forthcoming assignment, assumed the roles and responsibilities of the ailing crew member. With his timely intervention, the jet was steered safely to its destination without any further issues. The flight was met by emergency medical services on its arrival at the gate.

Air Canada, on the other hand, has remained unresponsive to requests for commentary regarding the event. Details pertaining to the specific aircraft involved were also not divulged by the TSB. However, according to the information available on the carrier's official website, Air Canada typically employs an Airbus A-220 twin-engine airliner for this route, a model with a passenger capacity of approximately 140.
