An off-duty pilot stepped in to help land a plane being diverted to Dublin Airport after a co-pilot fell ill.
The officer had been travelling as a passenger on a Lufthansa 747 flying from Newark to Frankfurt on Monday morning when it is understood the co-pilot suffered a migraine and was incapacitated.
Flight LH403 landed safely in Dublin at about 5.30am, Dublin Airport Authority confirmed.
A Lufthansa spokeswoman said the man who stepped in was fully licensed to fly the 747.
“In such circumstances it's normal procedure for the pilot, the flight captain, to continue to operate the aircraft,” she said.
“But the efforts of the off-duty pilot were certainly appreciated.”
The Irish Aviation Authority has been notified of the incident.
