As CGB and many many others have said, the weather at the impact point is irrelevant and it would be really good if we could just get on and accept that. I'm pretty sure 100% of forum observers would accept posts 6347 and 6351 and agree that it is only 'negligent' to deliberately fly below SA in IMC in open airspace.
We keep on having the Rip van Winkles wake up and shout 'they were IMC when they crashed' and 'they should not have been there'. Nice if they would just slumber gently on, really.
Could the RvW's accept we (probably) all agree? Could they accept that what we would actually like to know is why they were 'there'. Wratten and Day do not know.
