Shot by WNBC camera operator Craig White starting at 10:28:21 a.m., according to the NIST website (wtcdata.nist.gov requires agreement to copyright terms [for cookie], then reclick this link if necessary). This angle is very similar to three others: APTN Below North 1 and 2, and one by WPIX. This one doesn’t include the initiation, though.
An additional, identical clip (but shorter) also in the NIST FOIA release 14 is NBC_News Dub from Jim RembergNBC News Dub_clip27. Another high quality version is in release 25, 42A0118 – G25D28.
