Yep, there were loads of explosions on 9/11 because there was loads of fire. Fire causes explosions. As to blast explosions; famously, the US has loads of guns and ammunition; the public have a constitutional right to carry them. Either the AFT office or the US Customs House (WTC5 or WTC6?) had a sizeable ammunition store.
Reports of explosions don’t indicate “controlled” demolition; for the top-down collapses of the Twin Towers, you’d need a descending wave of blasts, timed to produce the descending collapse front. The Twin Tower collapses were recorded on countless videos; each Twin Tower fell with a roar, not a fusillade.
What about the countervailing reasoning? The supposed “controlled” demolitions had to be initiated at each tower’s damaged zone. Each was a site of major fire, and had been subjected to something resembling a fuel-air bomb when the aircraft struck (massive fireballs recorded on video). How were these critically important demolition materials, including explosives, supposed to withstand around 45 minutes and 90 minutes of intensive fire? It’s absurd.
