Mr Walker
I understand your grief and sympathise completely. I also knew Roy, who died with your son.
I'm not so sure this public site is somewhere you may want to attempt to try and highlight your mission.
The AAIB report is quite codemning in regards to some poor judgements and operations outside of the priviledges of the licenses held by those involved.
I hope you are able to accept some realities and mourn successfully rather than become some Al Fayed character.
Both Andy and Roy are sadly missed. There is not one father who does not understand your loss.
