Forty slate angels grace the memorial site - each marked with the name of one of the forty heroes of Flight 93. A nearby angel plaque reads:

"Few can begin to understand what drives
men to such acts of desperation.
But the World must now know
the resolve of this great nation is both
unshakeable and unstoppable.

This ordinary Americans took
extraordinary steps to help their
fellow Americans and by doing so
gave the greatest sacrifice.

And so these Angels of Freedom stand
not as a memorial to those who died,
But rather as a celebration of their lives
for which we will be forever in their debt.

God Bless the Families and Friends of the
True Heroes of September 11, 2001."
