Slaughtermeyer, those sources are hardly credible. For one they never address the 400-odd missing people from the four crashed flights.
For two, one suggests a NUKE brought down the towers. A small, bunker busting nuke..which would still produce a significant amount of radiation and would *not* lead to the towers falling in on themselves. Reach much?
For three, they reference each other and use THAT as proof. Excuse me if I fail to find a conspiracy site citing another conspiracy site as reliable.
Site #2 *****es about it being a "hit piece" and then tries to rebutt it the same way. They also deliberately misinterpret things people said- asking to pull the firefighters out becomes "blow up the building". (I have *never* heard anyone use the term "pull it" to refer to blowing something up..but that's what they claim)
They also note the towers were designed to take a hit from a plane. What most of them don't mention is that the towers were designed to take a hit from a Boing 707. The biggest 707 has a maximum takeoff weight of 333,600 pounds. The 767 on the other hand has a maximum takeoff weight of 410,000 pounds. That extra 80k pounds probably screws things up just a little.
Your last link doesn't work. Here's a Google Cache link:

Its also a publishing note, not an official church stance.
