Clockwork Mouse, have you read the SI, in particular the sections on culture, flight preparation etc? It is clearly written, evidenced and in my view damning. I can see why SLW has reached his conclusions, although they may be a tad OTT considering the tragic circumstances of this thread.
The SI uses a number of theories to explain why cultures like this can begin and perpetuate. Gouldie's post shows to highlight how people can fall into the trap of believing that everything is fine "our core output is IT/doing air shows etc. and that's going well so everything else must be fine".
The Reds are not the only unit to suffer from small unit syndromes such as these, look at the SI into the almost sinking of (now former) HMS Endurance on the same gov.uk website to see some very similar themes.
