ST;
No indications whatsoever. Then again I've yet to hear of a 109 that could carry 8 people (legally anyway).
Straight away the uninformed speculation starts. I don't know why the AAIB bother, they should just read the posts from the "experts" here and in the general media.
I had a text naming the pilot earlier, if it is true then that pilot is a very experienced operator.
