Barack Obama and John McCain are observing a one-day truce in campaigning to observe the 9/11 anniversary today. The campaigns agreed not to run any negative ads for the day.
The two will appear at Ground Zero for a wreath-laying ceremony this afternoon followed by a joint appearance at Columbia University to discuss public service.
At a ceremony in Shanksville, Pennsylvania - location of the Flight 93 crash site - John McCain and his wife Cindy layed a wreath and the Senator delivered the following statement:
"No American living then should ever forget the heroism that occurred in the skies above this field on September 11, 2001. It is believed that the terrorists on United Flight 93 may have intended to crash the airplane into the United States Capitol. Hundreds if not thousands of people would have been at work in that building when that fateful moment occurred, and been destroyed along with a beautiful symbol of our freedom. They and, very possibly I, owe our lives to the passengers who summoned the courage and love necessary to deny our depraved and hateful enemies their terrible triumph.
"I have witnessed great courage and sacrifice for America's sake, but none greater than the sacrifice of those good people who grasped the gravity of the moment, understood the threat, and decided to fight back at the cost of their lives.
"I spoke at the memorial service for one of them, Mark Bingham. I acknowledged that few of us could say we loved our country as well as he and all the heroes of September 11 had. The only means we possess to thank them is to try to be as good an American as they were. We might fall well short of their standard, but there is honor in the effort.
"In the Gospel of John it is written, 'Greater love hath no man than this: that a man lay down his life for his friends.' Such was their love; a love so sublime that only God's love surpasses it. I am in awe of it as much as I am in debt to it. May God bless their souls."
