Hi Dave,
Lightoller was desperately trying to save himself at the time when it was pitch dark.
At the time the forward funnel fell, the lights had not yet been extinguished. It was only *after* the bow had plunged before momentarily "checking" that the lights went out for good. This is clearly indicated by steward Edward Brown's testimony:
10557. When the afterpart of the ship gave this tremble, where were you then? - In the water, right before the forward funnel
10558. Did you notice whether the lights of this afterpart were still lighted of not? - There were lights burning then.
10559. Could you see that? - Yes.
Emily Ryerson's affidavit also tends to suggest that the two forward funnels fell before the lights were extinguished;
The two forward funnels seemed to lean and then she seemed to break in half as if cut with a knife, and as the bow went under the light went out...
The weight of evidence supports the theory the submerging bow was by no means "pitch dark" at this juncture, and I am, therefore, inclined to give Williams the benefit of the doubt on this, although admittedly, there faling funnel scene in Cameron's scene is too brightly lit, giving a misleading picture
Best Regards,
Ben
