They normally start with the "Controlled Demolition" argument for WTC 1 and 2, which is normally rebutted without difficulty..they then segue into the WTC7 collapse and try to make that the focus (We haven't seen the "pull it" quote referenced in this thread yet, but we will, we will). Normally the Pentagon comes last, and we've seen the first reference to the tapes question.
Ah, but the argument for controlled demolitions hasn't been refutted. There is a lot of evidence to support it...and the official story just doesn't make sense. Unfortunately, because the evidence was detroyed before being investigated...(and a few volunteers getting to see some debris at the Fresh Kills landfill doesn't count...) was shipped out and destroyed. Why would they destroy it so quickly if they really wanted to know what happened? As far as the pull it quote...yeah that does raise some questions. I don't agree with others who yell, "ooh! He admitted it!" Some think that it means to demolish, some think that it meant to pull firefighters out of the building. Many reports have showed that there weren't any firefighter operations in the building at the time, and I believe that he said it to distract people from the fact that explosives were there before 9/11. The average American watching PBS wouldn't have known that you need days, even weeks to plant the explosives needed to take down a building like that.
As far as the tapes...we ask because there isn't a good answer. Why would they have a reason to tell the employees at the hotel to not talk about what they saw? What are they hiding? To simply brush it off as, "that's what they do..." is just crazy. Never trust your goverment, always question it, otherwise, you let them take control. The government is supposed to be our servant, not our master.
At least this particular bunch of CT'ers seems to be grounded enough to concur that it was commercial airliners that hit the buildings (I could be wrong and we have yet to hear from CptFarlow on the Pentagon to any great degree). But always the same arguments. Nothing new. Seen it once, seen it again.
I have heard a few quotes of people claiming the planes didn't look like normal ones, with the "blue logo" on the front...but these don't prove much at all. We have seen evidence of wreckage from the plane, with windows, at the scene. While it may be possible, I do believe that those were real commercial planes. I am not ruling out that they may have been drones, it has been planned before.
The Pentagon raises a lot of questions, no doubt you have all heard. Many believe that a missile hit the building, many believe it was a smaller plane. Others say it was a huge 757. I don't know what it was, but I don't believe it was a huge jetliner. The wreckage at the site doesn't match up with it. Within minutes after the impact, employees were out there to clean up the wreckage and take it to a waiting truck. You have all most likely seen the picture of the employees covering something with the blue tarp, carrying it by hand, and having it taken away. The other evidence was picked up by hand by other employees. What was under that tarp? If it was part of the fuselage of the 757, why take it away? How would they be able to carry it? As far as the hole, it is quite small...you can't deny that. There is no impact where the engines would have barreled into the building, and there is no real evidence that a plane hit the building. The official explanation is that the jet fuel vaporized the fuselage. It can easily be found that titanium boils at 5949 degrees F. Vaporization takes place well above even these extreme temperatures, so to think that the jet fuel from the few seconds of impact could cause temperatures this high is insane. How would they have been able to identify any of the DNA if temperature had reached that high? No biological matter could have survived.
Also, look at any list of passengers for those flights that day. See any Arab names? Nope. Look up the autopsy reports...nope, no Arab names at all...strange. But it doesn't matter, right? Dubya said it was terrorists, so let's just go with that...it doesn't make sense, but let's go with it.
Lastly, you said it's the same stuff, every time. Well, let me ask you something. To prove that person A killed person B, you don't go across the world and dig up person ZKDS and question him, he knows nothing of Persons A and B. What I am trying to say is, it's the same evidence because this is what doesn't make sense. I'm human just like all of you, so I surely can make mistakes, but so can you. I am still not fully convinced that there is a whole conspiracy, but there are just too many unanswered questions for me to let it go.
