I will say again, I believe we learn nothing from wild speculation! If you wish to learn from others mistakes look at the AAIB reports.
We all have ideas about why people crash but to actually learn we must have the full details not parts of ,or speculation. I am not after censorship but rubbish about a flight plan(not needed) or the merits or not of N-reg (maybe another time) don't help or explain the reasons why.
I will say no more on the matter.
