NEW YORK - Defense Secretary Leon Panetta took a somber walk through the National September 11 Memorial park and museum, kicking off a series of Sept 11-related events to mark the 10th anniversary of the terrorist attacks.
Panetta's visit in a driving rainstorm gave him an early glimpse at the memorial, with its majestic 30-foot manmade walls of water that hug the sides of one-acre reflecting pools that encompass the ground where the Twin Towers stood. The water is meant to signify falling tears.
Panetta also took a peek inside the entrance to the museum, which is still under construction. And he was shown the "Survivor Tree," a non-fruit bearing pear tree that was rescued from the World Trade Center grounds after the terrorist attacks. It stands amid the white oaks, near the reflecting pool at the former South Tower.
Dozens of workers scrambled Tuesday morning to put the finishing touches on the memorial, planting ivy as ground cover around the 225 white oak trees that surround the reflecting pools.
Panetta had planned to also visit the partially completed memorial in Shanksville, Pa., where hijacked United Flight 93 crashed in an open field, killing all 40 passengers and crew members. But the weather forced officials to cancel the trip.
The Sept. 11 attacks killed nearly 3,000 people, including 184 at the Pentagon. The names of every person who died in the attacks -- including those at the Pentagon and at Shanksville -- are inscribed into bronze panels that edge the reflecting pools at the twin towers site.
Panetta's spokesman, Doug Wilson, said the Pentagon chief wanted to visit Shanksville and New York in order to highlight the role the military has played over the past decade in preventing further attacks on the homeland. Accompanying him on his trip Tuesday were five service members - one each from the Army, Navy, Marine Corps, Air Force and Coast Guard.
The visit was also likely to recall the most memorable event of Panetta's tenure as CIA director: the May killing of al-Qaida leader Osama bin Laden.
Panetta will attend 9/11 memorial events at the Pentagon on Sunday.
He was a private citizen on 9/11 but happened to be on Capitol Hill at the time of the attacks, according to his press secretary, George Little.
Shanksville remains the least publicized of the three 9/11 attack sites. In its final report, the official 9/11 Commission that investigated the terrorist plot wrote a gripping account of what happened aboard Flight 93.
The commission determined that the plane, overtaken by four hijackers, slammed into the ground at 11 seconds past 10:03 EDT, on a path over Pennsylvania toward its intended target in Washington - either the Capitol or the White House.
It departed from Newark, N.J., bound for San Francisco, at 8:42 a.m. The hijackers took over the cockpit 46 minutes later. At 9:57 a.m., a passenger revolt began. The cockpit voice recorder captured sounds of the passenger assault.
"Some family members listening to the recording report that they can hear the voice of a loved one among the din," the 9/11 Commission report said.
Within minutes, the hijackers apparently determined they were about to be overpowered and decided to abort their mission and destroy the plane. "The aircraft plowed into an empty field in Shanksville, Pa., at 580 mph, about 20 minutes' flying time from Washington, D.C," the report said.
