The great thing is everyone can access the United States Senate Inquiry Board testimonies and the British Wreck Commissionary Inquary Board testimonies at http://www.titanicinquiry.org/index.html and read the actual question to the crew/survivors taken back in 1912. Here you get the facts from those who were there and saw the great ship go down. The testimonies hold many facts that when combined with other testimonies of other shed light never reported or portrayed. How the Titanic sank is written in the testimony of those that were there you must read between the lines sometimes. I read the inquiries regularly and find new and interesting facts regularly.

Did you know that the water tight doors were reordered open after the iceberg was struck? And never reclosed! Read #3737 & #3792

Water never gushed in from gashes in the starboard side.

There are stories in the testmonies "if" you seek.
