I would have no worries at all if anybody I knew was onboard. As I work in aviation (and presumably most people on these forums do) then I am well aware of these things happening fairly often so I would have less worries reading it here than if it was on the news channels. By the time these things are on PPrune it has all happened anyway and if a serious incident or accident the news channels would have the first reports.
I read these forums to find out what is happening, good or bad. If you don't want to know the bad then just stick to the innocuous titles, don't open anything mentioning accident or emergency.
