Radar,
I think that Mr Walker has a very accurate understanding of all the factors behind the accident.
I hope that the Coroner will be in a similar position, and will investigate, thoroughly, the circumstances of the flight.
In my opinion, there is little benefit in examining who was 'in command' (whether on paper or de facto). Of greater interest are the background to the flight (the reason why the aircraft would fly to its destination and back), the development of the plan for the flight to take place, the motivation both felt by and placed upon those involved, and the promise and delivery of favour then and in the future.
Supersport, if you are as immune to normal human response to motivation as you claim, then you are unique indeed...
