Forget: There is much more to CC's job than safety during take-off and landing. Inflight medical emergencies, inflight fires etc - these are all part of the safety aspects of the role of CC.
What type of A/C crewed this flight, and how many crew do BA usually have on said type?
I would be interested to hear from crew involved in this - see how bad injuries were, how they were consulted, why the decision was made to continue as opposed to returning etc etc
