National Geographic - Secrets of the Titanic
On DVD, the images from Ballard's dives are crisp and clear, as if the viewer were visiting the wreck in a glass-bottomed boat. Extras include a photo gallery of stills from the dives along with vintage photographs, aTitanicroute map, and a short trivia quiz. The best bonus is a 20-minute feature,Last Hours of the Titanic, in which Ballard talks about the difficulties of locating the wreck, the mechanics of the ship's demise, and how he and his team pieced together a composite picture of the sunken ocean liner. This DVD is an excellent resource for anyone fascinated by theTitanic's doomed voyage.--Larisa Lomacky Moore
