U.S. Mail carton from United Airlines Flight 93
In 2002 Congress directed the Smithsonian Institution in Public Law 107-117 to "collect and preserve...artifacts relating to the September 11th attacks." Both the National Postal Museum and the National Museum of American History have collected artifacts under this directive.
This portion of a U.S. Mail carton was recovered from the debris of United Airlines Flight 93, which crashed in Somerset County, Pennsylvania, on September 11, 2001.
Both mailers and the United States Postal Service use lightweight, plastic cartons for loading and unloading mail to expedite the distribution process.
