Ragman,
Welcome to 'prune.
As you appear to be relatively new here I guess you might not realise that the findings of the AAIB will be published in due course after a very thorough examination of all the known
facts.
This may take many months or even over a year.
( Although an Interim report may be published sooner than that with any initial findings. )
It is only 8 days since this unfortunate incident, and it has not yet been possible to even formally identify some of those on board,
let alone determine the cause.
unfortunately it will come out as that by what has been said
Hmmm -
Fortunately the AAIB findings will not "come out" as a result of the comments on here !
