Nonsense such as 'would you take off without a full tank of fuel?' and 'no one knew where to look because the pilot didn't issue a mayday' demonstrate the agenda clearly.
Why do you think that stuff is nonsense?
If you are flying to a remote aerodrome known for having unpredictable weather, why would you only load the legal minimum fuel? Why not fill to your MAUW?
If you're going to do a controlled ditching with power and some time to prepare, why wouldn't you put out a mayday including your actual position? Why wouldn't you give the passengers enough time to get life jackets on?
Why was the Captain out before the passengers?
I think these are valid questions for this type of show to be asking and I'll be interested to read the ATSB report when it comes out.
