As Friends of Flight 93, we welcome worldwide all who would join us in honoring the sacrifice and courage of the passengers and crew of Flight 93 by supporting the mission of the Flight 93 National Memorial with volunteers, resources, and civic engagement, so as to inspire all who visit with the Flight 93 story.

Volunteers planting tree seedlings at a national memorial.



We have reached our goal of 150,000 new tree seedlings! The reforestation project has been a collaborative partnership that is shared by state and federal government agencies and both private and academic organizations. Reforestation is part of the memorial’s original design and is meant to reclaim the former surface mine with native trees.

This year, nearly 500 volunteers has helped with the planting of approximately 14,000 seedlings over twenty acres. Since 2012 more than 4,200 volunteers have planted 41 varieties of native trees and shrubs across 197 acres at Flight 93 National Memorial. These trees have formed essential windbreaks now that the trees are 8-feet tall. Much of what is now the memorial is a former surface coal mine and this effort has also re-established woodland wildlife habitats and cultivated a living memorial. The planting of these native trees and shrubs attracted 63 native bee species and 141 native bird species.

The Flight 93 partnership remains very grateful to the volunteers, supporters, and conservation partners who make this vital program possible each year.  For a full list of our reforestation partners (2012-2022), please visit

Smoke rising from crash

September 11, 2001 began as an ordinary, late-summer day. But, in less than two hours' time, this seemingly routine day was transformed when nineteen terrorists boarded and hijacked four airplanes to attack America.
