One of the links armchairpilot94116 posted is an article by Professor Peter B. Ladkin. His formal analysis of accident causality has had broad influence in aviation safety the past couple of decades. And, he often posts here in PPRuNe as PBL.
Actually, he has no posts since 2011. It was unfortunate that when he did, he came across frequently as completely arrogant when questioned on his opinion. Do a search and decide yourself. I was repeatedly insulted when I questioned his statements on the 757/Tupolev midair over Germany in which he stated that the Tupolev pilot was justified in ignoring the RA, which was directly responsible for that accident by the way. It was quite a disappointing attitude for someone who appears to have written some interesting information.
Anyways, back to thread subject.
