Pennsylvania ? With the words “Let’s roll” — the command issued by United Flight 93 passenger Todd Beamer to lead the passenger revolt — U.S. Interior Secretary Ken Salazar and 39 victims’ relatives and dignitaries turned shovels of dirt at a groundbreaking ceremony Saturday for a permanent national memorial.

“We made it. Not to our goal, not to the finish line. Certainly not any semblance of closure, but nevertheless, we made it to the next milestone of our journey,” said Gordon Felt, whose brother, Edward Felt, was one of the 40 passengers and crew who died when the plane crashed into a field near rural Shanksville, about 65 miles southwest of Pittsburgh.

The government intends to have the first phase completed by Sept. 11, 2011 — the terrorist attacks’ 10th anniversary.
