15日,美国总统奥巴马为911博物馆揭幕.历经了三年的延误,争议及经费困窘后,911博物馆终于落成.
CBS News reports more than 13 years after the attacks of Sept. 11, the completed museum at the World Trade Center site opened its doors. US president Obama toured the museum.
The collection of artifacts, pictures, videos and stories of victims fill the museum - a Pandora's box of memories that pay tribute to the tragic events that unfolded in lower Manhattan, as well as Washington D.C. and Pennsylvania, on that terrible day.
