I watched several 100th anniversary Titanic specials, but some highlights:
I just saw an amazing new special on the Titanic that said that Titanic no way would have sunk were it not for the refractive effects of the atmosphere that night. The iceberg they hit was camoflouged by a mirage for 30 minutes and did not clear up until the last few seconds, and by then it was to late.:
on coast to coast, a famous ocean archaeologist, Charles Pellegrino:
described the rusticles and details of the remains .
A tremendous series of specials did justice to this fascinating topic.
