The question has been answered...and honestly, you won't accept any answer unless it supports your delusional fantasy.<quoted text>
You never answered my question Charlie.
Why did the firefighters not realize that the WTC was going to collapse, since the event made it so obvious that NIST failed to check for explosives and accelerants?
Insults Are Easier
NIST indirectly tested for explosives through visual examination and through the positive material identification testing done on WTC steel.
No signs of explosives were found rendering the need to test for explosives moot.
Oh but you continue repeating and re-repeating your silly little twoofer approved meme...it's all you have.
