A plane landed safely in Boston Logan International Airport on Wednesday after the captain experienced medical problems mid-flight, authorities said. 

The Air Canada flight was traveling from Newark, New Jersey, to Halifax, Canada, with 61 passengers on board, the airline said in a statement.

Shortly before 1:40 p.m., State Police were notified that the aircraft was being diverted to Logan Airport after a crew member was reported to be experiencing a “medical emergency,” State Police said in a statement. 

Air Canada confirmed the captain was the crew member who suffered a medical issue.

Authorities did not specify the nature of the emergency. State Police said they could not provide additional details about the pilot’s condition, but told CBS News that the captain had become “incapacitated” during the flight.  

According to Air Canada, the captain was removed from the flight deck in accordance with safety protocols.

“The first officer took control of the aircraft and diverted the flight to Boston, where it landed safely,” the airline said. “Pilots are trained to fly aircraft and land safely without the assistance of a second pilot.” 

As the flight approached Logan, State Police patrols and the agency’s Marine Unit were deployed as a precaution. Massport Fire Rescue and Boston EMS also responded, according to Massport officials.

After the aircraft landed without incident, the alert for the matter was terminated at 2:24 p.m., police said.

The captain was transported to a Mass General Brigham hospital for evaluation, State Police said. 

No update on the pilot’s condition was immediately available.

Air Canada said it is working to arrange onward travel for passengers affected by the diversion.
