A BA pilot suffering with food poisoning fled the cockpit to be sick in the loo - just as the plane was coming into land at Heathrow.
The captain of the Boeing 747 was then forced to follow safety procedure before landing the plane on his own.
A British Airways spokesman told The Sun: "He was sick in the toilet just outside the cockpit door.
"He couldn't return to the cockpit, so the Captain followed all the relevant safety procedures. The aircraft touched down normally."
A source told the paper that the incident, which happened in March 2012, was "harrowing" for the pilot - and the passengers who saw him fleeing the cockpit.
The British Airline Pilots Association (BALPA) said the co-pilot did an "exemplary job" in landing the plane safely.
A BALPA spokesman told MailOnline: "Events like these are fortunately rare, but they show the professionalism and skill of pilots when they do.
"The workload for a single pilot landing an aircraft on his or her own is tremendous and he appears to have done an exemplary job in this case."
The news comes just a week after BALPA revealed more than half of pilots have fallen asleep in the cockpit.
On Sunday, a pilot admitted to falling asleep at the same time as his co-pilot during a flight, just days after it was reported that two Virgin Atlantic pilots suffered "severe fatigue" and had to take turns resting on a Transatlantic flight to the UK.
The pilot says he and his co-pilot were coming to the end of a long overnight shift and were due to land a freight plane to Spain.
