In 2005, a History Channel expedition to the wreck site scrutinized two large sections of "Titanic"s keel, which constituted the portion of the ship's bottom from immediately below the site of the break. With assistance from naval architect Roger Long, the team analysed the wreckage and developed a new break-up scenario which was publicised in the television documentary "Titanic's Final Moments: Missing Pieces" in 2006. One hallmark of this new theory was the claim that "Titanic"s angle at the time of the breakup was far less than had been commonly assumed—according to Long, no greater than 11°.
