The 1998 Titanic documentary Echoes of Titanic was recently released on DVD in 2012 for the centennial as part of the Titanic Definitive Documentary Collection. You can get it on Amazon here: https://www.amazon.com/dp/B005X7H9SQ/?tag=encyclopediatita. I recently checked out this DVD from my local library, and I noticed they edited out a shot of the World Trade Center from the New York scenes from the original VHS tape. The Twin Towers can be seen in this video at 1:33: I think they should have kept the shot, it's better to keep the towers instead of editing them out, it makes it seem like they never existed at all. It's better to keep them in respect for the 9/11 victims instead of removing them. I'm glad Gangs of New York kept the Twin Towers at the end.
