Footballer Emiliano Sala and his pilot David Ibbotson were exposed to harmful levels of carbon monoxide before their plane crashed, it has been revealed.
They were both killed when the aircraft came down on January 21 in the English Channel.
The Air Accident Investigation Bureau said that prior to the crash the cockpit had filled with the deadly gas.
The pilot’s body has never been found.
The Air Accident Investigations Branch (AAIB) took his body to Portland before being passed over to the Dorset coroner, who formally identified it as Sala.
Daniel Machover, of Hickman and Rose solicitors, lawyers for the Sala family, said: ‘That dangerously high levels of carbon monoxide have been found in Emiliano’s body raises many questions for the family.
‘How he died will be determined at the inquest in due course.
The family believe that a detailed technical examination of the plane is necessary.
‘The family and the public need to know how the carbon monoxide was able to enter the cabin.
Future air safety rests on knowing as much as possible on this issue.
‘Emiliano’s family call on the AAIB to salvage the wreckage of the plane without further delay,’ the lawyer said.
