FILE - In this Tuesday, Aug. 20, 2002 file photo, a woman looks a copy of "Let's Roll!" by Lisa Beamer at Sam's Club in West Windsor, N.J., after it went on sale. Beamer's husband, Todd, died when hijacked United Airlines Flight 93 plunged into the Pennsylvania countryside on Sept. 11. Before the crash, a cell phone operator heard Todd Beamer say "let's roll" as he and other passengers attempted to overpower the hijackers. (AP Photo/Daniel Hulshizer, File)
