Hoots,
Speculation on the cause of an accident or incident is human nature, especially within the aircrew community. Inevitably on a forum such as this some speculation will be better informed than others.
Unusually in this case the 'spin' started with anouncements about technical failures even before the aircraft type had been released.
It is useful to separate speculation threads and condolences ( I take the earlier point that family and friends may read both). This protects to a degree the feelings of those closest.
Ultimately though this IS a rumours network and even if some of the speculation may not turn out to be a causual factor in this case, the fact that aviators (and hopefully the BOI) have discussed it may leave it fresh in ones mind should it become a factor in the future.
That in itself is useful as it could one day save someones neck, in the same way that crewroom WOTIFS discussions can.
