SOMERSET — A task force set up to establish a memorial at the Western Pennsylvania site of the crash of Flight 93 is to disband this week, now that the memorial is under construction.

The executive committee says the task force will disband after Saturday's meeting with a Flight 93 federal advisory commission in Somerset.

The Flight 93 Memorial Task Force began with 80 members and eventually grew to 100, made up of family members, people from the surrounding community, emergency responders and others.

Flight 93 was traveling from Newark, N.J., to San Francisco when hijackers took it over on Sept. 11, 2001. It crashed in a field near Shanksville, killing everyone aboard.

The first phase of the memorial is expected to be dedicated in time for the 10th anniversary of the crash.
