Just standing on the sidelines - I retired a few years back after 46 years flying with QF - it seems to me that AIPA needs to seek legal advice from Ron Bartch. Ron is the leading aviation lawyer in Oz so he has clout in any court given that he wrote the text book.
This whole thing makes me glad to be out. Would I really take such a big punt and fly these crazy TOD like 22+ hours?? Maybe when I was young and keen but no way after I grew up. What if it causes massive problems in 10 years? Who knows? I'm not immune to the lure of something new, I loved the long haul flying to BA over Antarctica and the operational problems needing to be solved. Actually I love flying, silly old me!!
