As part of its continuing investigation into the crash of a motorcoach that occurred in New York City last year, the National Transportation Safety Board (NTSB) added more items to the public docket.

On March 12, 2011 a motorcoach, operated by World Wide Travel of Greater New York Ltd., collided with a roadside barrier adjacent to the southbound lanes of Interstate 95 in the vicinity of mile marker 3.2. Fifteen of the 32 passengers on board were killed; 17 passengers and the driver suffered minor to serious injuries. The motorcoach was returning to New York City from the Mohegan Sun Casino in Uncasville, Conn.

Forty-six photographs and 83 documents totaling more than 1,600 pages have been added to the docket. The information being released is factual in nature and does not provide any analysis. It is available now, here.
