Aha! Maybe now we can investigate the steel from the WTC
WTC steel found buried at ground zero
NEW YORK – Large steel columns from the fallen twin towers have been found beneath a service road being excavated at ground zero in the search for long-buried Sept. 11 remains, officials said Wednesday.The surprising discovery of World Trade Center steel in the past week raises more questions about what was left at ground zero in the cleanup after the 2001 attacks and how the service road was created in the first place.
</em>Now, perhaps, an actual forensic investigation can be made on the steel from the World Trade Center- the bulk of which was sold off for scrap soon after the event, with no examination.
