WTC 1: NIST unaware of earliest antenna, north wall movement
Careful observation and measurements reveal that the earliest detectable movement leading into the collapse initiation sequence is that of the antenna and the northwest corner of the building.
Upper West Wall Pulls Inward 9.5s before Collapse
Antenna Base Shifts Eastward 9.5s before Collapse
This movement, beginning almost 10 seconds before the first visible movement, went unnoticed by the NIST and is not mentioned in the NCSTAR reports.
