9/11 Unanswered Questions:

Structural & Collapse MechanicsTiming, Evidence & Anomalies
1. Why did large portions of the WTC towers’ distinctive checkerboard outer shell remain largely intact even after the core columns had supposedly been destroyed? Why were the steel girders severed into consistent ~30-foot lengths that conveniently fit onto standard trucks?7. Why did the second-hit tower (WTC 2) collapse first, before the first-hit tower (WTC 1 with the antenna/mast)?
2. What caused the central spire/core to appear to dissolve, beginning with the visible descent of the antenna? Why did the pyroclastic-like cloud behave like a fluid, flow along the ground like water, coat people in thick dust, and then seemingly melt upward into the sky?8. Why does seismic data reportedly show activity prior to the actual collapses, and how does this align with explosions propagating as pressure waves? What is the relevance of the 42 military drills on September 11, 2001?
3. What was the “lather-up event” involving apparent cold-fusion weakening? Why did observers across the river report smoke or vapor emanating uniformly from the entire surface of one side of a tower?9. Why were the Air Traffic Control (ATC) tapes related to the events destroyed?
4. Could the towers have been brought down through resonant destruction similar to a wine glass shattering from sound waves? What proportion (if any) of the massive steel core and perimeter columns fragmented into much smaller pieces?10. How were the hijacked airliners able to maintain structural integrity and fly at speeds of approximately 550 knots at low altitudes, given known airframe instability issues?
5. Why did the top ~25 stories above the impact zones (particularly in WTC 2) tilt more than 12 degrees and then become completely pulverized rather than falling as a coherent block?11. Why did FEMA personnel reportedly arrive on site the day before the attacks?
6. What was the source of the molten metal observed pouring from the buildings prior to collapse? Why was the father’s lawsuit dismissed after his son died from intense flames inside an elevator before either tower collapsed?12. How were passengers and crew able to make successful 9-1-1 and personal cell-phone calls from the hijacked planes in 2001, given the limitations of cellular tower technology and the absence of cell repeaters on commercial aircraft?
