I am not speculating, just thought I would check the conditions that have been posted on prune regarding this sad accident as an exercise (for my benefit) from the tables provided as a guide found in most ops manuals and the UK CAA AIC's. No one seems to have highlighted this point yet and its pertinant to all ops not just the Challenger. Food for thought when considering fatigue and commercial pressure.
Regarding the 850 accident at Moscow didnt that have some problem with its nosewheel steering??? On a contaminated runway???
Safe flying to all for 2008
