Thanks. Interesting, then, (if it was serviceable) that there is no mention here of what the Captain might have seen on the installed camera system impacting on his "no evacuation" decision?
I was going to say the incident should strengthen the case for such camera systems to be fitted to all large aircraft - but if it was not used/not working/not seen to provide useful information in this case then in fact the incident rather erodes the case for fitting them a little.
