right , i do hope you are joking , terrorist bombs to take out the two of them? the buildings both fell perectly "textbook demolition" if you will in all fairness it could have happened but its unlikely , taking into account that it takes weeks to prep a building for demolition , and then to fit the explosives. i think they would have noticed a load of arabs running about drilling holes in the walls this is unlikely. now in a realistic situation you would need a large quantity to take out one of the trade centers, i mean look what happened in '93 , was a mere scratch. now for it to have happened they would have needed to get these large quantitys of explosives in there at somewhere in decent relation to the structure to get it to fall , now on one of the towers , its a possibility for a few men to get in and plant it inconspicuously , amidst the mayhem , but in two towers? no way and if it was done in a rush there was not a hope in hells chance of getting two f**king huge towers to fall perfecty straight. now taking into account the quantity of the explosives needed , it would be too great to be done incognito. then also the quality of explosives it would probably be something cheap , semtex or something. would never be able to do it that quickly , secretly and effectively
