So this flash that Gibson saw 'apparently on her deck' sprang out of the sea just as he saw the streak of the signal go skyward and then burst into stars. OK, that's surely must be insignificant in comparison to unreliable subjective estimates on the distance of lights seen at see at night. I suppose if this signal came from Titanic, then it would have been impossible to see through binoculars what Gibson described seeing from a vessel that was 22 miles away. We should simply reject all that Gibson had wrote to Lord. He was obviously making it all up.
