Not really, no. The emergency dynamos were well above the waterline, being fed no doubt by the last remnants of steam from BR#2 (these were fed from Boiler Rooms Nos. 2, 3, and 5, but by that point, 3 and 5 were so far forward and under that anything left was likely coming from No. 2). I've heard some interesting theories about certain things with the dynamos and how they could have failed, but the most important thing to remember is that the survivors largely seemed to recall the lights failing and the noises that accompanied the breakup as being simultaneous. Like I said before, however, we discovered over a decade ago when first researching the breakup appendix for the book OASOG that there were multiple eyewitnesses who described lights on after the break.Would there have been any reason (besides the break) for the lights to go out? From what I’ve read, the main lights went out during a loud noise.
I also loved seeing the reported “shower of sparks” go in the air during the break. I think that’s the first time that has been depicted in anything. I can’t recall who said it, but I remember someone saying that the sparks seemed to light up the whole scene for a second and you could see everyone and everything in the water around the stern.
You also asked:
>>>And speaking of loud noises/“explosions,” do you think that the reported four *bangs* as the bridge went under had anything to do with the correction of the port list/slight rising of the starboard side?<<<
In short, it would seem that way, yes. Lightoller referred to the plunge probably having something to do with a bulkhead going; the way it happened, looking at it from all angles as we did and could as we prepared the animation, reading survivor accounts of the noises that accompanies that 'slight but definite plunge', it did seem like something did give way that allowed water to rush into a previously unflooded portion of the ship. We can't be dogmatic about it, but Lightoller's hunch on this point tended to ring true for us as we worked on this.
