It appears that Emiliano Sala and David Ibbotson were exposed to high levels of carbon monoxide poisoning in the cockpit before crashing.
Could this be the reason why someone was arrested in connection with the crash a couple of months ago? The gas produced is normally conveyed away but there seems to have been a leak in the ventilation system.
Indeed, although David Ibbotson's body hasn't been recovered and it's very likely that it never will. Must be awful for his family not being able to lay him to rest.
Interesting. I knew a pilot who crashed and died at an airshow. I heard suggestions of carbon monoxide poisoning at the time but nothing was proved. He was ex Red Arrows and very experienced. It's a shame when a crash could have been preventable
