I will go on record!
The FATAL crash was due the unsurvivable nose down impact with the Earth even thou the seats could survive a 500 g impact.
The eye witness seems to know a bit more about the flights around his turf than others.
Trained investigators are employed by the same folk as our governing CASA employees, many of them I find hard to call experts or even capable of much in aviation.
So lets wait for the report from the experts.
For the record I think it is a +50% or close 50/50 this may be a non pilot issue and a external factor may be involved.
