What I witnessed on the morning of 9/11 was unique in regard to all of the other research data you may have seen. Put yourself in the shoes of the planners. And not just the planners, but those whose job descriptions were intimately connected with live operations. Failure is not an option.

YOUR job is to record to HD/_uplink THE definitive view of the second hit. This is the one that matters most because every aspect of the event depends upon believability. So, you position the camera at quite a distance and as nearly parallel to the incoming 'plane' as you can find. ((A known perspective.)) From this vantage point, you pre-frame the action. Trained in video, and perhaps sport, this job feels very much like shooting basketball. You absolutely must capture the hoop, and enough reference material to indicate who is moving through the frame of action.

Let's say it's also absolutely vital for this image to make its way to the control tower, ostensibly Building 7. This procedure is simple enough for any non-engineer in the broadcast profession. You simply open a channel on the back haul. But, not just any back haul will do, you'll need to use a blind resource channel, out of phase with the standard local broadcasters which will become a saturated air-space by the time frame-for-frame analysis becomes due. Based upon this pre-positioning awareness, YOUR images technically reside historically as THE primary smoking gun. CGI remains of secondary analytical value.
