Pprune is unique in that it was designed as a forum for professional pilots but is now open for anyone to come on and express their opinion. You would never find an open forum for professional surgeons where people with no medical experience or training could post their criticisms of surgeons and they how they could do it better.
There are some situations where frankly it is best that passengers did not know what is happening, ie dispatching with technical difficulties, reroutes resulting in minimum fuel, commiting to a destination airfield without fuel to divert. Professional issues where there are rules and standard procedures may sometimes come as a surprise to what a passenger might expect. This is thread is typical where someone has described a situation thinking it is unusual and may have been badly handled when it is actually quite common and has probably been properly handled. Some of the initial posters clearly think a diversion was merited and expressed outrage that it did not happen. A lot of professional pilots no longer read this forum due to the drivel frequently expressed by emotive people who may be very competent in the field they work in but do not understand a lot of the basics of running an airline.
