Local buzz all seems to suggest both engines functioning...took off but didnt climb..then tanked in going flat out....which all seems consistent with the massive destruction.
Thats very interesting as it stacks up with my earlier theory from the video footage of possible instrument failure during departure in foggy conditions resulting in a high speed impact.

My personal thoughts looking at the video is a high speed impact which would not be conducive with an engine failure and loss of control occurring at a relatively low speed.
Given the nearest metar at the time;

I would be interested with investigating possible instrument failure leading to disorientation shortly after take-off, main engine shaft and propellor damage will provide evidence of engine failure or under power at the time of the crash.
