Dublin cabin crew had to undertake updated training after an Aer Lingus flight was forced to an emergency landing after smoke filled the cockpit.
The A320 was flying from Cork Airport to London Heathrow on November 2, 2017 when crew noticed fumes filling the cabin, forcing it to return.
The same Airbus jet - EI-GAL - regularly serves Dublin Airport , and just today was returning to the capital from Barcelona.
But after landing in Cork, some panicked passengers opened the emergency doors and climbed onto the wings of the aircraft in a bid to get out as quickly as possible.
There were 143 passengers on board as well as six crew who were all forced to make an emergency evacuation shortly after returning to Cork, says the report from Air Accident Investigation Ireland.
But 32 people left by the emergency doors after the Captain told them to get off the plane immediately.
And a man travelling on the flight, known as Passenger A, told the investigation while the pilot was excellent, the evacuation was chaotic.
He said that some passengers did not know what to do and some opened the overwing emergency exits.

Passenger A disembarked through one of these exits and stood on the aircraft wing where two other passengers were assisting people through the emergency exit.
He said that the escape slide looked deflated and he was told by a Fire Officer not to use it.
He also told the investigation that the evacuation procedure was frightening and that adults and children were upset, which caused him to feel upset.
He later began feeling unwell and was admitted to hospital, but his was the only reported illness in relation to the emergency landing.

The Captain told passengers: “Attention, attention, this is the Captain. Disembark the aircraft immediately, disembark the aircraft immediately.”
The passengers began to leave, with some choosing to use the overwing emergency exits.
When the Cabin Crew realised that the overwing exits had been opened, a second announcement was made by the senior cabin crew members.
They said: “Ladies and gentleman, please remain calm and please exit the aircraft through the back doors and the forward doors.”
Cabin crew were investigated following the incident and said that a combination of factors may have led to the chaos that unfolded following the landing.
They said that fire crew surrounding the plane with hoses, the PA system sounding louder than usual and not knowing the difference between a ‘disembark’ and ‘evacuate’ instruction could have influenced how passengers perceived the situation.
While cabin crew all receive training in dealing with fume events, it was found during a simulation of the flight that there was differences between it and the real-life situation.
A planned upgrade to the cabin simulator will help crew better prepare for future incidents, Aer Lingus have said.

The report said: " Aer Lingus has reviewed the training that cabin crew receive to prepare for such incidents.
"They determined that cabin crew training in this area could be strengthened by improving the capability of their in-house cabin simulator.
"The Operator plans to upgrade the simulator in 2019 to include the Cabin Intercommunication Data System.
"This will allow the Operator to simulate a variety of cabin electrical equipment failures."
The plane, EI-GAL, was cleared the fly shortly after the incident with problems from the avionics blower fan found to be the cause of the fumes.
The Airbus A320 regularly serves Dublin Airport, returning to the capital from Barcelona today.
