Then explain how it was that the side lights of both vessels were mutually visible by Lord, Groves, Stone and Gibson from abut 11pm April 14 until just after the Gibson saw rocket number 5 ? If those on Californian could see the other vessel's sidelights during that time, then observers on the nearbt vessel could see the lights of Californian. Had that other vessel been Titanic, then the observers on Titanic were much higher that those on Californian so could see a great deal farther.I suggested nothing of the kind. I suggested that the green was invisible because the Californian wasn’t close enough to the Titanic. At the time she got close enough her green was closed, and her red was opened.
In truth, those on the nearby vessel, saw Californian's lights from the moment that nearby vesel stopped until that vessel turned away and steamed off to the SW'ward. It is cruel to whip a "dead horse".
