The pilot of the plane that crashed killing footballer Emiliano Sala was not licensed to fly the aircraft, a report has found.
Sala, 28, and pilot David Ibbotson died in the crash, two days after the Argentine striker signed for Cardiff City in January 2019.
The Air Accidents Investigation Branch published its findings on Friday.
It said Sala would have been “deeply unconscious” from carbon monoxide poisoning at the time.
Sala was travelling from Nantes, in France, to Cardiff on 21 January 2019, when the single-engine Piper Malibu N264DB aircraft in which he was travelling lost contact with air traffic control north of Guernsey.
Mr Ibbotson lost control of the plane while descending to avoid cloud and he was probably also affected by carbon monoxide, the Air Accidents Investigation Branch (AAIB) concluded.
