FILE - In this June 17, 2011, file photo, people touch a 12-foot steel beam from the World Trade Center during the beam's arrival from New York City in Wauseon, Ohio. Pieces of steel from the twin towers have been parceled out to all 50 states and eight countries for memorials and museum exhibits and were used in the construction of the U.S. Navy ship USS New York. Of 2,200 pieces of steel preserved in an airplane hangar in New York City, there are fewer than 30 left.

In an airplane hangar at New York's Kennedy Airport, fewer than 30 pieces of steel remain from the debris recovered after terrorists flew hijacked planes into the World Trade Center's twin towers on Sept. 11, 2001.

Even 14 years after the attacks, applications are still pending for the pieces of metal — mostly for memorials and museum exhibits — and some pieces found a new home as recently as last week in New Hampshire, Massachusetts and Florida.

Here's a look at what has become of the relics of the World Trade Center:

How much steel?Beginning in August 1968, builders used 200,000 tons of steel to build the World Trade Center complex, enough to raise the twin towers to heights of 1,362 feet (south tower) and 1,368 feet (north tower).Out of 1.8 million tons of debris removed from the site after the attacks, recovery workers collected 840 pieces of steel, some of which were cut up to make a total of 2,200 separate items. They ranged from 6-inch slabs to massive beams to the 7.5 tons the Navy used in the construction of the warship USS New York.

<b>Where did it go?</b>The artifacts can be found anchoring memorials or museum exhibits in all 50 states and eight countries: Germany, Canada, Brazil, South Korea, The United Kingdom, Afghanistan, China and Ireland.The Port Authority of New York and New Jersey oversees the artifact program, reviewing applications and parceling out the steel and other items to about 1,500 individual nonprofit groups, governments or museums so far. The artifact must be available for the public to view it.

<b>Cranberry Memorial</b>Cranberry Township broke ground for a memorial in front of the Park Fire Station on Route 19 on the 10th anniversary of the attack with the focus on a damaged 832-pound steel beam recovered from the wreckage of the World Trade Center. It was dedicated a year later.Two granite slabs shaped like the World Trade Center hold up the damaged I-beam. The concrete base of the monument displays the city block around Ground Zero in New York City to show what the area looked like before the attacks. The memorial is positioned so that people can walk up and touch it.Cranberry firefighter Jeff Berneburg headed the memorial committee and presided over the lengthy application process and eventually traveled with firefighter Bruce Hezlep, now a township supervisor, to New York City in April 2011 to pick up the beam.<b>How much is left?</b>Fewer than 30 pieces of steel, including pieces of rail tracks, remain. Fewer than 70 other artifacts such as clothing or toys also remain in Hangar 17 at Kennedy Airport.<b>Are items still sought?</b>Yes. Thirty applications are pending approval, and 40 others are in the review process.Even as recently as last week, an 8-foot-long, 1,100-pound steel beam arrived in Portsmouth, N.H., while other pieces were distributed to Ware, Mass., and the Kennedy Space Center in Florida during August.The Ware Fire Department is building a second memorial using trade center artifacts. It received a 1,600-pound piece of steel in August that will be used in a memorial that is still being discussed.At the space center, the beam will be the centerpiece of a permanent memorial at Fire Station No. 1. That memorial includes small-scale replicas of the twin towers.<b>Was any of the steel recycled or discarded?</b>No. The Port Authority's mission was to preserve the artifacts and distribute them to worthy groups to memorialize the attacks.<i>SOURCES: The Port Authority of New York & New Jersey; the New York State Museum; Associated Press archives; and staff reports.</i>
