I've read your paper. Regarding your claims about NIST "making up" their times, this description of how they reconstructed the timeline from the visual record is relevant:
Recognizing that the majority of timing information available from the visual material itself was of high relative accuracy, but of unknown and variable absolute accuracy, a timing scheme was adopted in which all of the times for items in the databases were placed on a common relative time scale tied to a single well-defined event. Due to the large number of different views available, the moment when the nose of the second aircraft struck the south face of WTC2 was chosen to be this time. This event was defined to have occurred at 9:02:54 a.m. based on times for major events included in the earlier Federal Emergency Management Agency (FEMA) report (McAllister 2002) describing the events of September 11, 2001.
Once the reference time was chosen, it was possible to place times on videos that showed the second aircraft impact. By matching other photographs and videos to these initially assigned videos, the assignments were extended to visual materials that did not include the primary event. Using this process it was possible to place photographs and videos extending over the entire period of the event on a single time time line. Sets of photographs containing EXIF times and video clips that either contained metadata or were continuous over relatively long periods were particularly useful for this purpose, because a single time assignment would allow the entire series to be timed. Sets of photographs recorded on film or analog videos that were frequently turned on and off were the most difficult items to time since individual matches were required for each photo or video clip.
Matching visual images and assigning times turned out to be a demanding task, requiring unique approaches. A variety of characteristics were employed to match times in different photographs and videos. These include distinct shadows cast on the buildings by the smoke plumes, the appearance and location of smoke and fire plumes, the occurrence of well-defined events such as a falling object or the sudden appearance of smoke, and a variety of other unlikely clues such as a clock being recorded in an image.
A visual record exists starting with the first plane impact; in fact, this event was captured on two different videos. After that, there were a
lot of cameras aimed at the WTC. But I digress.
To assist in the timing process, relative times for the five major events of September 11, 2001-first aircraft impact, second aircraft impact, collapse of WTC2, collapse of WTC1, and collapse of WTC7 were determined with 1 s accuracies.
What NIST did was to organize the recorded images into a relative time line, partly by using metadata in digital images, which would give relative times for a series of pictures taken with the same camera or digital video clips from the same recorder and partly by comparing identifiable features and events in separate images. The second sentence I've bolded in the first quote sums it all up- they ultimately derived a timing for the different events which showed how far apart in time they occurred.
To correlate this relative timeline with absolute time, they began with the assumption that the time given for the
second aircraft strike of 9:02:54 was correct. Using this assumption, they found that the
first aircraft strike would have occurred at 8:46:25, which differs from the FEMA reported time of 8:46:26.
This does not support the contention that NIST's initial absolute time determination for the first impact was based on LDOE data or from FEMA and therefore not coupled to the absolute time for the second impact derived from broadcast timestamps. Rather, it indicates that NIST's intial absolute time for this event was derived by determining the time interval between the first and second impacts
from the visual record and referencing it to the assumed absolute time of the second impact. This means that the two times were in fact coupled together by the time line reconstructed from the photo and video evidence and that an offset correction to one would properly apply to the other.
Their initial time determinations for other events, such as the collapses of the twin towers, also differ from those given by FEMA; in the case of the first collapse by 10 seconds and in the case of the second collapse by 14 seconds. This is more evidence that NIST relied on FEMA timings
only for the absolute time of the second impact and derived all other times by reference to the visual data.
All of the times given in the "relative time from visual analysis" column of table 3-1 are just that- derived from the visual record and related to the time of the second aircraft impact. Since all of these points do indeed lie on the same "ruler", a correction to the location of its "zero" reference point applies equally to all of them.
It's possible to question the accuracy of NIST's approach, although without re-doing all of that tedious comparing and calculating and databasing it's impossible to support a contention that it's wrong.
But I don't see how a claim that they "made it all up" can possibly be supported by this evidence.
Handwaving. That's all the PCT position has got.
