The legacy of Flight 93

Graham Satchell reports from Shanksville, Pennsylvania

Flight 93 was headed for Washington - probably the White House.

It never got there. With the now infamous words "let's roll", the passengers fought back.

They forced the plane to crash in Shanksville, Pennsylvania.

the memorial is a few miles outside Shanksville

This is small town America.

The people of Shanksville describe it themselves as a place that time forgot: in the middle of nowhere.

Dutch, the oldest man in town, whiles away the hours on his porch talking to anyone who happens to pass by.

The sign says its a friendly little town. But there's also an edginess here: it is overtly patriotic. The American flag is everywhere - it's a place forever in the shadow of tragedy.

"Its something you think about everyday even a year later you don't get out of bed without thinking about flight 93, " says Terry Shafer.

He was the first to get the call. It was 10.06am on September 11.

"When we arrived there was literally nothing we could do. There was nothing left of the plane bigger than the hood of a car.

"It had all been smashed into little bits. It's a day the firefighters here will long remember."

Less than a mile from Shanksville, deep in rural Pennsylvania, there's a traffic jam.

They come to see what remains of flight 93. Not much is the answer.

The temporary memorial to flight 93 its little more than a car park, but every day hundreds of Americans come from all over the country to leave mementoes and read what other people have written.

Bea still longs to hear her son's voice

Some of those I spoke to at the memorial believe that America has changed: there's been a loss of innocence.

Most people in Shanksville still have a strong faith in God. But many of the other certainties in small town America have gone.

Pastor Sylvia Baker says: "Americans have always felt like we've got it all and we know what we're doing : who can touch us? Well we found out the hard way."

Jerry and Bea Guadagno thought nothing could touch their family - certainly not terrorism.

In a quiet cemetery in Trenton New Jersey, they tend the grave of their only son.

Richard Guadagno had flown to New Jersey for his Grandmother's 100 th birthday - that was September 10. The next day he flew home on flight 93.

Bea tells me: "All I wanted was to see him coming in the door and hear that call Hi Mom which I will never hear again.

That to me has been taken away - there's a hole in our hearts that will never never be replaced."
