The commission oversaw the building of the Wall of Names near the crash site of Flight 93 in Shanksville, Pa.
The Flight 93 Advisory Commission, created by former President George W. Bush after the Sept. 11, 2001 terrorist attacks, is disbanding.
The 15-member group, appointed by the Secretary of the Interior, helped plan and design the memorial at the site where hijacked United Airlines Flight 93 crashed during the attacks, killing all 40 passengers and crew.
The meeting will coincide with the ground breaking for a learning center and a separate visitor center at the Flight 93 National Memorial near Shanksville – about 215 miles west of Philadelphia.
Jeff Reinbold, the memorial's superintendent, calls the move to disband “a sign of success.”
The group has met four times a year since being sworn in nearly 10 years ago.
“This will be a big change -- no matter what was going on we always knew the group would be coming together four times a year,” Reinbold told the paper. “The commission led the planning, design and construction of the memorial. We are transitioning from the partners of the early days when we were thinking of what the memorial could be and should be to seeing it built.”
