If these "theorists" put half the effort into debunking the fake theories as they did into trying to prove the ridiculously absurd claims, like hologram-projected planes that don't exist, we would have this shit figured out by now.
I can't help but think the video of it in slow motion looks fake.

There is no way an airplane would submerge itself fully into a steel framed building without at least a wing or tail fin getting ripped up. Really, you can't slam your fist on an airplane's nose or wings without making a serious dent. Regardless of how much it weighs in total or how fast it is going, the steel still provides an intense amount of strength and cannot be sliced by aluminum airplane wings. I haven't found any reliable eye-witness accounts of actually seeing this 2nd plane or the first one for that matter. I have seen accounts of people saying that they saw the explosion, but definitely did not see a plane.
Look at this shitty CGI visualization from Perdue U. Go fly an airplane into some strongly rooted and secured steel columns and see what happens in real life.

As to the nuke...it may not have been, but those 2 wtc's didn't simply collapse, and some carefully placed conventional explosives could make at least large portions of the building collapse, but really, the towers were nearly disintegrated, mostly blown to bits. Sure there were some "wheat chex" of steel left, but not much. There are still too many strange occurances such as the arcing debris being propelled from the building, the scorched metal blocks away, the crater with a cooled magma-like appearence, the weeks long smoldering buried rubble, the large expanding volcano-like cloud that did not occur over wtc7 demolition, but did occur over 1 & 2, the vast amount of conventional explosives needed to create such an event, the thyroid cancers and skin tumors of wtc cleanup crews, the tritium in the ground water...
There are pictures and links to what I just listed in previous pages of the thread. Don't ask me to provide links again.
