SHANKSVILLE, Pa. (AP) — Gov. Tom Corbett and his wife on Saturday joined volunteers who are planting thousands of trees at the Flight 93 National Memorial in southwestern Pennsylvania.
Corbett and first lady Susan Corbett laid flowers at the memorial wall before an event honoring the 33 passengers and seven crew members killed when the plane crashed into a field on Sept. 11, 2001, after passengers fought back against hijackers, the governor's office said.
"We are planting these trees not only in their memory, but in honor of the futures they assured for countless citizens by planting the first seeds of resistance to assure our nation's freedom," Corbett said.
About 600 volunteers are planting about 15,000 trees on 23 acres this year at the site about 60 miles southeast of Pittsburgh. More than 150,000 trees are to be planted at the site.
United Flight 93 was traveling from Newark, N.J., to San Francisco when it was hijacked by four terrorists. The 9/11 Commission said the terrorists likely wanted to crash the plane into the White House or the U.S. Capitol, but the jet went down in a field near Shanksville, Pa., after passengers fought back.
