A contributory factor to the Kegworth BMI 737 accident were the ATC requests made on the crew during a period of very high workload. Should be seen in context with the well-known inter-cockpit issues in that accident; prioritisation, clarity of decision making processes, use of SOP's and more.
Agree with the Naked Pilot recommendation above, also check out Stanley Stewart's book on accidents, the name of which escapes me right now.
