Former Presidents Bill Clinton and George W. Bush will speak Saturday at the dedication ceremony for the United 93 Memorial in Shanksville, Pa., the National Park Service announced Thursday.
Vice President Biden will also deliver remarks at the official opening and dedication ceremony for the memorial at the site, a field where the United 93 airliner crashed after it was hijacked on Sept. 11, 2001.
House Speaker John Boehner (R-Ohio) has also announced he will attend the event, along with a bipartisan congressional delegation.
“If not for the heroes onboard United 93, who challenged the hijackers and forced them to abandon their plan, it is quite possible that the Capitol, and the people working inside it, might not be here today,” Boehner said last week in a news release.
The event will also feature a wreath-laying ceremony and a performance by singer Sarah McLachlan.
The memorial is the result of the Flight 93 Memorial Act, signed into law by Bush in 2002, which created a new national park to commemorate the crew and passengers of the flight. The dedication event marks the transition from a temporary to a permanent memorial for the site.
United Flight 93 was hijacked on Sept. 11, 2001, and likely would have been flown into the U.S. Capitol had passengers not fought with the hijackers and caused the plane to divert to Pennsylvania, where it crashed.
