Carmody probably didn’t write the letter. He most likely received a brief from senior management that finished with the recommendation that he sign the attached letter.
Carmody most likely received glens letter, went WTF? Then handed it to the very people who were torturing Glen for to craft the official CASA response.
NOBODY at that level does anything on their own. Carmody knows sfa about aviation. He would have had to ask and possibly been told that Glen was a wacko troublemaker with an axe to grind, such people exist and Carmody’s letter looks like exactly the response you normally. send. At least it didn’t threaten him with an AVO and the Federal Police.
