Cazatou:
This was not an SAS insertion in a combat zone but a routine Passenger transit flight to be conducted under VFR in accordance with the rules and regulations pertaining at the time.
I believe the rules and regulations pertaining at the time required there to be 'No doubt whatsoever' before bringing in the verdict that the ROs imposed overriding the BOI findings. I suppose Air Rank (or being on the staff of these skygods) allows you to ignore inconvenient rules?
