Glen, in my opinion, it’s over and you lost. Unless you have a knight in armor in reserve or can galvanize public support, there’s nothing you can do. You have been branded as a nutcase by CASA and the Ombudsman has accepted that. Do you need me or someone to spell it out ?
The response of the DAS and Board is now predictable and negative. Unless you can immediately generate considerable industry support or have a judges opinion in your favor it seems to me that you should cut your losses and look after your mental health. There is life after aviation. Get help.
