SYNOPSIS
During cruise the First Officer (F/O) began to feel unwell. His condition deteriorated progressively while the aircraft was over the North Atlantic Ocean. The Commander was advised by a doctor on board that the F/O should be brought to hospital and a decision was taken to divert to Dublin. An experienced captain with a different airline, who was travelling as a passenger, was identified by the cabin crew and assisted the Commander with cockpit duties for descent, approach and landing. Following an uneventful landing the F/O was taken to hospital by ambulance.
