A purse containing keys and a wallet recovered from the World Trade Center site. Seat belts and a flight attendant call button salvaged from the doomed United Airlines Flight 93. The desk telephone U.S. Solicitor General Ted Olson answered when his wife, Barbara, phoned from a hijacked airplane.

These deeply personal artifacts are among dozens of rarely seen objects on view this week at the Smithsonian's National Museum of American History, marking the 25th anniversary of the Sept. 11, 2001, terror attacks through searingly human details.
