A plane in Russia was forced to make an emergency landing after its pilot died out of a fatal heart attack while they were in the cockpit.

The plane was flying from Moscow to Anapa, a popular Black Sea resort, when it had to make an emergency landing at the Platov International Airport in Rostov-on-Don, a southern area in Russia.

After the emergency landing, authorities and paramedics made efforts to revive the pilot, but the efforts failed.

A spokesperson of Aeroflot, a Russian State Airlines, confirmed the news through a statement.

The statement said, “Unfortunately it was not possible to resuscitate the pilot.”

The statement added, “He died in the ambulance. We express our sincere condolences to his family and friends.”

The Aeroflot flight left the Sheremetyevo Airport in Moscow at 8:20 am and landed at the Platov International Airport in Rostov-on-Don by 9:57 am.

Flight SU1546 was flying at 33,000 ft. when the captain sought an immediate emergency landing at the nearest airport.

According to a passenger that was on the plane, a female flight attendant ran through the plane and asked the passengers if there was a doctor on the plane.

During an interview with a local press, a passenger said, “A female flight attendant ran through the plane asking if there was a doctor because one of the crew members was feeling unwell.”

The passenger added, “Several minutes later we were told that the aircraft was performing an emergency landing.”
