 Incident: British Airways A20N near Zadar on Dec 26th 2020, first officer incapacitated

A British Airways Airbus A320-200N, registration G-TTNM performing flight BA-640 from London Heathrow,EN (UK) to Athens (Greece), was enroute at FL310 about 20nm north of Zadar (Croatia) when the captain decided to turn around and return because the first officer felt unwell. While enroute back to London the captain indicated he might need to divert perhaps to Zurich (Switzerland) or Paris (France). The first officer became incapacitated (unconscious) about 45nm west of Zurich prompting the captain to decide to divert to Zurich. The aircraft landed safely on Zurich's runway 14 about 90 minutes after turning around near Zadar and taxied to a remote stand.

The aircraft remained on the ground in Zurich for about 5.5 hours, then continued the flight and reached Athens with a delay of about 9 hours.
