A Swiss Air flight from Bucharest to Zurich was forced to make an emergency landing in Graz, Austria, on Monday evening due to engine problems and smoke in the cabin and cockpit.

The Airbus A220-300, carrying 74 passengers and five crew members, landed safely, but one crew member was seriously injured and airlifted to a hospital.

Four other crew members and ten passengers also required medical attention.

Passengers described the evacuation as calm and professional, despite the frightening situation.

Graz Airport was temporarily closed following the incident.

Swiss Air has launched a task force to assist passengers and investigate the cause of the emergency.
