Dagens Tosse: patriotsquestion911/#Kurttila Conclusion: The observed collapse time of WTC 7 was 6.5 seconds. That is only half a second longer than it would have taken for the top of the building to fall to the ground in a vacuum, and half a second shorter than the falling time of an apple when air resistance is taken into account. ... The great speed of the collapse and the low value of the resistance factor strongly suggest controlled demolition. Heikki Kurttila, D.Sc. (Tech.) (Doctor of Technology) – Safety Engineer and Accident Analyst, National Safety Technology Authority (TUKES), Finland. Specialist in the investigation of pressure vessel explosion accidents and the impacts of the shock waves caused by them. 30 years experience.
