Of course Chippendale wouldn't have considered any of this as he worked for CAD and old shredder was his personal adviser. Whether he acted in a biased fashion or was just way out of his depth is a debatable point.
There are some unknown facts related to this crash, such as why the decision to descend was made when it was, why it continued with the weather, cloud base as it was, these facts will never be known.
But there are facts that are known, and the number of times in this thread that these have been distorted, or been completely wrong, time and time again, despite the correct proven, references given facts, physical impossibilities that some of the arguments are constructed on, no wonder it goes on and on.
Chippindale did not work for CAA. His office was completely independant, he reported directly to the Minister of Transport. The reason for this should be perfectly obvious.
