Some extras for today's 9/11 story

(Photo: fragments of the wreckage from Flight 93, part of the 9/11 exhibit at the National Museum of American History)

As always, any one piece I write is only a small part of the story, and that's never been more true than this week. My first column on this 9/11 journey came out this morning. Here are a few little extras to fill out the frame.

Here's the 9/11 collection at the National Museum of American History. This includes items that aren't part of the exhibit I saw Thursday. One thing I didn't mention: The artifacts in the exhibit aren't behind glass -- they're simply set down on tables, out in the open. You can't touch them. But somehow the lack of barriers makes the exhibit more intimate.

For another take on objects from 9/11, here's a New York Times slideshow on things people kept from the World Trade Center wreckage.

And here's one more photo I took at the museum. People who went through the exhibit were able to write a note about what they thought and post it on a bulletin board.

Sorry for the blurry photo. Here's what it says above the heart: "I will pray 4 these families even though I am very young I understand what happened. I hope you continue to do this to help people understand what happened now. I'M SO SORRY."
