You are talking rubbish first of all it was a B-25 that hit the empire state building not a B-52 which is quite a big difference in size 19,000lbs vs 185,000lbs empty weight.

Also the Trade towers were designed to withstand the impact of a 707 traveling at 600mph and still be standing they also said it could probably withstand multiple plane strikes and still be standing, so your whole argument is garbage.

Also they were doing construction work on the building leading up to the attack and were laying network cables iirc, there was a guy who complained about all the dust coming through the vents and when he asked he was told they were doing construction but when he went up the the floor above there was no one there as they were inside the central column but he could hear them drilling and doing something. He also went in to the building in the days before they fell and someone had turned off all the cameras and security and people were wandering around the tower, this annoyed him as iirc he was in charge of IT for banking servers and workmen were just wandering around without a care in the world which was really odd as you generally don't allow people in and around the servers unsupervised. So they had plenty of time to set charges if they wanted too.

Found him it was Scott Forbes https://www.youtube.com/watch?v=8edYhemleXc&t=10s

Scott Forbes was employed by Fiduciary Trust Company International, located on the 97th floor of the South Tower at the WTC complex. He says there were some very strange events in the weeks leading up to the attacks, including; a complete power down of the building for over 36 hours, and mysterious ‘engineers’ doing work in the building using spools of wire just days before the 9/11 attacks.
