My main interest is in the ship's maintenance.
When the power went out, there were no external emergency lights to be seen. I'd have thought that if a ship suffered a total loss of power, that several battery systems would come online and light it up to prevent other vessels at sea crashing in to it, and if it suffered a breach, to light up the path to the lifeboats. Yet it just went totally dark, like a ghost ship. Going by the power repeatedly coming on and off in the short clip we've seen, it's possible that this ship was struggling for some time and that the
ATS couldn't take it any more and packed up.
I'd also like to know how a ship of this size managed to get itself in to this situation in the first place. The amount of safety and alarm systems in place to prevent this exact type of scenario taking place would have had to be immense, unless it's a 40 year old 3rd world vessel running on 10p coins. That captain's deck will likely have lit up like a Christmas tree several times before getting to this point. And I don't mean in the last few minutes, I mean the last few days, if not weeks.
The investigation is certainly going to be interesting, I suspect we're going to see a company cutting corners, ignoring engineers, and forcing their staff to continue sailing despite the obvious warnings.
