NBC News wonders where 9/11 debris went

I just caught the tail end of the ad for it, but it looks like NBC news at 11:00 tonight will be investigating what happened to all the debris from the World Trade Center. Might be worth a look and if someone can tape it and post it here, all the better!

Should be on in about 5 minutes!

EDIT: Ummmm, OK, maybe not tonight! The only part of the ad I missed was when the piece was going to be on. Maybe this week, then...
