There are conspiracies and there are conspiracies. They're not all alike, and some would be much, much easier to pull off than others. The fewer people involved, the easier they are to carry off successfully. (To be successful, a conspiracy must not only achieve its aims; the fact that it was a conspiracy and the conspirators themselves must also remain undiscovered.)
An buttbuttination is a relatively simple act to carry out -- few people must be involved, logistics are relatively simple, it can easily be done in a covert manner because of its limited scope, and it would be easy to make all those "in the know" disappear afterwards. I believe it is very likely that there have been buttbuttinations that were planned and carried out by conspiracy.
Planning and carrying out a conspiracy like planting explosives in the twin towers, arranging to have planes flown into them, then bringing the towers down with the previously planted explosives AND COVERING IT ALL UP would require -- how do I say this -- *organizational skills not previously demonstrated by the Bush administration*. Too many people would have to know about it, and to succeed AND not be discovered is very, very unlikely.
