Corrected entry: Eric Braeden, playing John Jacob Astor, is shown on boat deck level of the grand staircase when the glass dome collapses from the weight of the water. But when the real Astor's body was found, it was terribly crushed and covered with soot. In all likelihood, he was one of those unfortunates who was caught beneath the falling forward funnel.

Corrected entry: When the liferaft with the officers aboard returns to try and search for survivors in the water, one Officer shout's, 'Is anyone alive out there?' There is a distinct echoing. However, with just a flat ocean surely there is nothing to provide an echo of his voice.
Correction: Yes, there is - the iceberg.
Correction: It is not known how JJ Astor died. Check out this page for more details: http://ourworld.compuserve.com/homepages/Carpathia/page12.htm.
