I read the post from airpolice as referring to the interesting word of "disimproving" and although it is actually correct, it's not commonly used.
I don't believe he was offering any new insight into the crash, or providing some new opinion, that cannot already be understood from the crash report.
Then again I could be completely wrong. Succumbing to the power of internet forum misinterpretation is quite easy.
I met the P1 a couple of times a few years ago and was saddened to hear of the accident. He was a very nice, friendly bloke in my opinion.
