A fire has destroyed three administrative buildings at the Flight 93 National Memorial in Pennsylvania, and officials are concerned about memorabilia stored there.
The National Park Service says no one was injured when the fire broke out Friday afternoon.
The memorial and construction at the visitors center were unaffected. Both are about 2 miles from the fire, whose cause hasn’t been determined.
The buildings in Shanksville house the park’s headquarters, including the superintendent’s office. Officials say about 10 percent of the memorial’s archival collection was kept on site, but many objects were in fireproof safes.
Among the items was a recently donated flag that flew over the U.S. Capitol on Sept. 11, 2001. Its status is unclear.
All employees evacuated safely, and no injuries were reported, spokesman Mike Litterst said. He did not immediately know the cause of the fire but said in a statement that initial reports indicated “extensive damage” to the complex.
The memorial, still under construction in Shanksville, marks the spot where United Airlines Flight 93 crashed during the Sept. 11, 2001, terrorist attacks. The plane, which was traveling from Newark, N.J., to San Francisco, went down in a reclaimed strip mine after passengers fought back against its hijackers. All 33 passengers and seven crew members were killed along with the hijackers.
A memorial plaza was completed in time for the 10th anniversary of the attacks in 2011. It features a white stone wall, which traces the path of the doomed flight, with separate panels for each victim. There are plans for a 93-foot-tall tower with 40 wind chimes.
Officials have said they hope construction of the visitors center, which is estimated to cost $17 million to $23 million, will be finished by June. That would give park officials three months to install exhibits in time to open for the 14th anniversary of the crash.
The president of the Families of Flight 93, Gordon Felt, issued a statement expressing sadness about the fire and saying the group awaited further information on the cause.
All told, the park is expected to cost about $60 million. The government spent another $10 million for the land, which is about 75 miles east of Pittsburgh.
