Today's award goes to British Airways.
A British Airways flight was forced to make an emergency landing at Heathrow with one engine damaged and the other on fire after fatigued engineers worked on the wrong aircraft.
The covers of both engines blew off and one burst into flames on the flight of an A319 from London to Oslo in May 2013.
The pilot returned to the airport using just one damaged engine and made an emergency landing while chunks of metal from the plane, some weighing up to 37kg, fell across the runway.
. . .
The AAIB report said doors on both engines had been left unlatched during maintenance and made a raft of suggestions designed to prevent such an incident happening again.
The unlatching of the fan cowl doors had not been identified before the plane took off with 75 passengers and five crew on board.
The 50-year-old captain decided to make the emergency landing four minutes after take-off, with the aircraft suffering a punctured fuel pipe and a fire in the right engine.
Passengers and crew evacuated via the escape slides without injury.
A report highlighted a series of safety recommendations, including tackling crew fatigue and in-flight damage assessments.
The report heard two technicians observing the plane before take-off failed to notice the Airbus was the "wrong" aircraft.
There's more at the link, including a picture of the damaged aircraft in flight. How it stayed in the air, I'm really not sure.
BA expects me to fly with them, after they merely worked on the wrong plane and failed to button it up afterwards??? So much for standards at "the world's favorite airline" . . .
