A British Airways flight from London to Athens was forced to make an emergency landing in Zurich on Saturday after the co-pilot fell unconscious at his controls.
Passengers arrived in the Greek capital nearly nine hours after they departed from London.
The flight from London’s Heathrow Airport to Eleftherios Venizelos International Airport usually has a duration of just over three and a half hours.
The flight was forced to ground in Zurich after the co-pilot complained of feeling ill while the aircraft was hovering over the city of Zagreb, Croatia, with just over an hour of the flight left to go.
At the time, the pilot decided to return to Heathrow in London, a two-and-a-half hour trip, rather than continue the flight to Athens.
Soon after, his co-pilot passed out completely. Considering the severity of the situation, the pilot decided make an emergency landing in Zurich so that his ill colleague could receive the necessary medical treatment he needed.
After being forced to wait inside the grounded plane in Zurich for over five hours, the flight’s passengers finally made it to Athens on Saturday, the day after Christmas.
The co-pilot was released in good health after receiving a medical examination in the Swiss city. The reason for his sudden illness is unclear.
