Hur och när fick man in sprängämnen utan att det märktes?
Hur dolde man explosionerna från seismograferna?
Hur kunde man förhindra att bränderna antände sprängämnena?
Hur kunde man förhindra att de små försvagningssprängningarna antände resten av sprängämnena?
Osv..
Jag har ju redan förklarat för dig, vad är det du inte förstår?
“Demolitions are typically very small explosions,” Lerner-Lam says. “And, you wouldn’t record them anyway because they’d typically be aboveground, and too small to observe.” (pg. 63)
Seismologist Arthur Lerner-Lam
[...]But with the charges positioned aboveground instead of within the earth ... the Aladdin implosion
didn’t even register on the nearby seismograph at the University of Nevada, Las Vegas, according to geology professor Dave Weide.
Clearly, a demolition’s seismic signature, like its other aspects, is a function of its design. Staggering the detonation of hundreds of charges over time would minimize explosives-induced ground vibrations, which would probably be eclipsed in any case by the relief of strain as tens of thousands of tons of the Towers’ upper sections were severed from their bases, and by the much larger vibrations caused by rubble hitting the ground.
