Angel -glad you are OK and can tell this tale.
I presume that the AAIB will get invoved with this and also Health and Safety as there is a duty of care towards you from the company.
SAR is a specialised part of aviation and can bite you very quickly if you are not completely on top of the situation. I am surprised at the allegation that night deck training hadn't been done for some time. I know that the nights are short in the north during the months of May, June and July but that doesn't excuse not keeping your hand in.
I look forward to reading the AAIB report and learning something from it.
