The wife of Emiliano Sala's pilot has tearfully admitted "relief" at new evidence that suggests her husband was not to blame for the pair's tragic death.
An interim report by investigators suggested Sala had been exposed to a "potentially fatal" amount of carbon monoxide shortly before the crash, which happened over the English Channel on January 21.
The Air Accident Investigation Branch say Sala had a carbon monoxide level of 58 per cent in his blood, an amount that can cause seizures, unconsciousness or heart attacks.
It is suspected that pilot David Ibbotson is likely to have been exposed to similar levels aboard the Piper Malibu PA-46 aircraft, which was due to take the footballer to Cardiff from Nantes ahead of a £15m transfer.
In an emotional interview with Good Morning Britain, Ibbotson's wife, Nora, said she hoped the findings would clear her husband's name.
"It is a relief because there was a problem," she said.
"It was out of David's control. They couldn't smell it, see it, if he knew, he wouldn't have flown it.
"We have to try and stay positive. We want the results for Dave."
Sala's body has since been returned to his family in Argentina, with Neil Warnock and Ken Choo among those to attend the funeral in his hometown of Progreso.
However, Ibbotson remains unaccounted for, with Nora opening up on the family's agonising wait for answers.
"It's not having David back. We want him here," she added.
"Every day it is hard, because I haven't got David, I haven't got a body."
It is still not yet known exactly how the pair died, but the findings may well help to explain how Mr Ibbotson lost control of the plane.
The AAIB added: “When our investigation has concluded, we will publish a final report.”
A Cardiff City statement on the report said: "Cardiff City Football Club is concerned at the AAIB's latest report which once again highlights that the aircraft used for Emiliano Sala was not appropriate.
"We continue to believe that those who were instrumental in arranging its usage are held to account for this tragedy."
