9/11 memorial and museum

Artifacts from ground zero get a preview at the National September 11 Memorial Museum in New York. Among them is a cross made out of steel from the World Trade Center in the 2001 attacks. The museum opens its doors Thursday, May 15, to the 9/11 community -- survivors, rescuers and families -- almost 13 years after terrorists hijacked and crashed four airliners into the towers, killing nearly 3,000 people. The museum will open to the public May 21.
