WTC Attack September 11, 2001 from New York Police Helicopter

When NY City handed this video over to NIST it required that it be left intact. If you compare the timeline to the Trebeca Apartments video you will see that the helicopter was setting on the lawn before flying to the top of WTC 1. ~o~ "The City expressly reserves its rights in these materials, and requires that you obtain the City's permission prior to any reproduction, modification, adaptation, recompilation, or other derivative use of each DVD-ROM or portion thereof, including any still image extracted or derived therefrom, and that the City's permission be obtained prior to the commercial distribution of any video footage and of still or moving images extracted or derived therefrom in any medium, by sale, rental, lease, lending or other means."
