Neo,
as a current mil pilot who has followed this enquiry from the outset - indeed a friends father was killed in the accident, i hope you do not mind my responding. you raise some pertinent points.
first and foremeost the purpose of the Lords enquiry was not to positively determine the cause of the accident. the remit of the enquiry was to examine whether there was sufficient proof to show "with no doubt whatsoever" that the pilots were "grossly negligent" ie guilty of manslaughter.
the lords enquiry shows no more than there was sufficient doubt behind the grossly negligent verdict reached by wrotten and day. therefore the reputations of 2 outstanding aviators, husbands and sons has been restored.
as the raf refused to fit adr or cvr to the fleet we will never be able to positively determine the cause of the accident. despite an alarming lack of proof 2 air marshalls with a vested interest in the result returned a grossly negligent verdict.
the campaign has only been concerned with clearing the names of the pilots.
