Flight 93 National Memorial

The boundaries of the National Memorial extend from Lambertsville Road to U.S. Route 30 (Lincoln Highway), where the entrance is located. It is about 2,200 acres (890 ha), of which about 1,000 acres (400 ha) are privately held but protected through partnership agreements. The memorial site itself is a 400-acre (160 ha) bowl-shaped area, with 1,800 acres (730 ha) surrounding as a buffer.[13] In December 2002, landowner Tim Lambert donated 6 acres (2.4 ha) at the crash site and entered discussions with the Conservation Fund regarding an additional 160 acres (65 ha).[14] Using some funds donated from receipts for the film United 93, the Families of Flight 93 organization purchased 3 acres (1.2 ha) in the summer of 2006. The organization sought $10 million in federal funding to use for acquiring land.[13] In November 2006, the Conservation Fund acquired 100 acres (40 ha) as buffer land, to be managed by the Pennsylvania Game Commission.[15] PBS Coals Inc. sold 900 acres (360 ha) to the families' organization in March 2008.[16]

Svonavec, Inc. owned a 275-acre (111 ha) parcel, which was a reclaimed strip-mine. Michael Svonavec, working with appraiser Randall Bell, submitted a letter to the National Park Service in November 2003 with plans to build a museum and visitor's center on his land. Although the other property owners had sold their land for the memorial, Svonavec believed that the crash had increased the property value of its land to $23.3M, while the government only recognized the land as being worth its original value of $610,000. The Flight 93 Advisory Committee and the Families of Flight 93 wrote a letter to President George W. Bush, asking him to issue an Executive Order which would authorize the use of eminent domain to secure the land.[17] Instead, Pennsylvania Senators pushed an amendment through Congress which allowed the Department of the Interior to seize the land by eminent domain.[18] The question of compensation was unsolved, and so the case of United States v 275.81 Acres of Land was brought before a federal district court to determine proper compensation for the property. The court-appointed Commission concluded that the appropriate compensation was $1,535,000.[19]

The commission decided to select the design for the memorial through a multi-stage design competition funded by grants from the Heinz Foundations and the John S. and James L. Knight Foundation. The competition began on September 11, 2004; over 1,000 entries were submitted online.[20] In February 2005, five finalists were selected for further development and consideration. The 15-member final jury included family members, design and art professionals, and community and national leaders. After three days of review and debate, they announced the winner on September 7, 2005: Crescent of Embrace by a design team led by Paul and Milena Murdoch of Los Angeles.[9]

The design featured a "Tower of Voices," containing 40 wind chimes – one for each passenger and crew member who died. A crescent would have been formed by a circular pathway lined with red maple trees that follows the natural bowl shape of the land. Forty groves of red and sugar maples and eastern white oak trees were to be planted behind the crescent. A black slate wall would mark the edge of the crash site, where the victims are buried.

Bloggers and religious groups criticized the new design.[21] Jury member Tom Burnett Sr., whose son was killed in the crash, said he made an impassioned speech to his fellow jurors about what he felt the crescent represented. "I explained this goes back centuries as an old-time Islamic symbol ... I told them we'd be a laughing stock if we did this", Burnett said.[22] Representative Tom Tancredo of Colorado opposed the design's shape "because of the crescent's prominent use as a symbol in Islam". Mike Rosen of the Rocky Mountain News wrote: "On the anniversaries of 9/11, it's not hard to visualize al-Qaeda celebrating the crescent of maple trees, turning red in the fall, "embracing" the Flight 93 crash site. To them, it would be a memorial to their fallen martyrs. Why invite that? Just come up with a different design that eliminates the double meaning and the dispute".[23] The architect asserted that the alignment was coincidental and that there was no intent to refer to Muslim symbols, with which several victims' families agreed.[24] Al-Qaeda and its affiliated Jihadist groups belong to the Salafi movement, which generally does not consider the crescent to be a symbol of Islam, viewing it as a later innovation of purportedly less pious empires.[25]

Others criticized the design as too non-representational. James Lileks, a journalist and architectural commentator, wrote:[26]

We don't need giant statues of the guys ramming the drink cart into the door. But pedantic though such a monument might be, future generations would infer the plot. All you get from a Crescent of Embrace is a sorrowful sigh of all-encompassing grief and absolution, as if the lives of all who died on that spot were equal in tragedy. They were not.

In response to criticism, the designer agreed to modify the plan. The architect believes that the central elements can be maintained to satisfy criticism. "It's a disappointment there is a misinterpretation and a simplistic distortion of this, but if that is a public concern, then that is something we will look to resolve in a way that keeps the essential qualities", Murdoch said in a telephone interview to the Associated Press.[27]

The redesigned memorial has the plain shape of a circle, as opposed to a crescent. The circle's design is bisected by the flight's trajectory, which is marked by a clearing in the trees. The new design was supposed to emphasize the area of impact.[28] According to the memorial's architect, Paul Murdoch:[29]

... a walkway approaches from an arrival court along the edge of and overlooking the Sacred Ground. The walkway eventually widens in from a ceremonial gate . and the wall of names, composed of 40 panels of 3-inch-thick (7.6 cm) slabs of polished white granite, 8 feet (2.4 m) tall, each inscribed with a name of the 40 heroes. Two walls flanking the gate are clad in polished white granite and the flight path is paved with black granite. Beyond the gate is the impact site ... planted with wildflowers, and the hemlock grove beyond.

The cost of the permanent memorial is estimated at $60 million. As of March 2011, $20 million in private donations had been raised, the Commonwealth of Pennsylvania was providing $18.5 million, and Congress had appropriated $10 million;[30] the families of the victims of Flight 93 urged Congress to appropriate $3.7 million more in the fiscal year 2012 budget.[30] The permanent memorial was originally planned for dedication on September 11, 2011;[31] however, the pace of construction was delayed due to, among other factors, shortage of funding and the general economic downturn in America.

Ground was broken on November 8, 2009, at a ceremony led by Secretary of the Interior Ken Salazar and attended by Governor Ed Rendell, Senator Bob Casey, and Representatives John Murtha and Bill Shuster, as well as National Park officials, first responders, and family members of the passengers.[32] The Wall of Names was completed in 2011.[33]

In 2017, construction of a 93 ft (28 m)-tall monumental "Tower of Voices" began. The tower contains 40 wind chimes – one for each passenger and crew member who died in the crash, but none for the terrorists as they were responsible for the hijacking. The tower forms the gateway to the National Memorial and is visible from U.S. Route 30. The largest such structure ever built, the precast concrete tower supports polished aluminum chimes varying in length from 5 feet (1.5 m) to 10 feet (3.0 m) and varying tonalities (voices). The tower, built from 274 short tons (249 t) of concrete and steel, was constructed by L.S. Fiore.[34] The pitch of the chimes was conceived by composer Samuel Pellman and constructed by a wind engineering consultant, an acoustics engineer, and a musical instruments fabricator. Prototypes were tested in Simi Valley, California, Morton, Illinois, and the desert in Arizona – sites with similar wind conditions as the memorial, which is located in an area of relatively high average wind speeds and has wind farms nearby.[35][36]

Construction of the main tower was completed in 2018 and eight of the forty wind chimes were installed.[37] In September 2020, the remaining wind chimes were installed by ARCH Production & Design NYC[38][39] along with the mechanism that allows them to ring.[35]

The first phase of the memorial was dedicated on September 10, 2011, at a public ceremony attended by Vice President Joe Biden, former presidents George W. Bush and Bill Clinton, Speaker of the House John Boehner, other dignitaries and family members of the passengers, and thousands of others.[40][41] During the ceremony, Clinton announced that he and Boehner would launch a fundraising effort to raise the $10 million required to complete the memorial.[42][43] Singer/songwriter Sarah McLachlan performed both "Angel" and "I Will Remember You" at the dedication ceremony. The Bells of Remembrance were tolled 40 times, once for each of the passengers and crew as their names were read, a tradition from the annual September 11 observance.

The Tower of Voices was dedicated on September 9, 2018.[44]
