Yes, the WTC was not just two towers, but several buildings. The reasons people don't take issue with the others is bacuase they were crushed by debris and none of them appeared to implode.
WTC 7, however, was across the street and although there were some office fires visible late that day, it did appear to actually implode:
The collapse itself is certainly troubling for any of us with some common sense left, but beyond all that, we have shit like this:
That is not photoshopped from a "conspiracy" site. It is from the actual FEMA report in "appendix C."
That report is even titled:
Limited Metallurgical Examination
Beyond this admission in title, FEMA goes on to admit:
The eutectic temperature for this mixture strongly suggests that the temperatures in this region of the steel beam approached 1,000°C (1,800°F), which is substantially lower than would be expected for melting this steel.
Note they use 1,800°F because that, as we established is the absolute hottest that that fire could burn at. Their own story does not allow for these extremely high temperatures. They even conclude with:
C.6 Suggestions for Future Research
The severe corrosion and subsequent erosion of Samples 1 and 2 are a very unusual event. No clear explanation for the source of the sulfur has been identified.The rate of corrosion is also unknown....
A detailed study into the mechanisms of this phenomenon is needed to determine what risk, if any, is presented to existing steel structures exposed to severe and long-burning fires.

To my knowledge, this has never been done and I know why.
