Unable to post a link to the DT article. Gist of it is "Those in charge of helicopter safety warned that the upgraded HC2 model was not fit for service and that flying operations should cease immediately". This statement was made on the day that the crash occurred.
The well known aviation and legal expert John Hutton (Who he?) states that "No new arguments have been advanced to warrant the overturning of the findings" Another name to add to the list of incompetent top men who are shamed by their approach to this matter.
Dr Michael Powers QC, speaking for those fighting the finding, said "This Chinook was so unreliable that the very people charged with its safety had reached the conclusion that they would not let their test pilots fly it"
