NIST, Building 7 & The Seismic Readings

In 2006 NIST was asked about the damage and seismic impacts from 2 x 500 000 ton buildings slamming onto Liberty Plaza, especially the pipes underground leading to Building 7 - What do you think did NIST have to say?

Then in 2023, I asked the "9/11 truther celebrities"
What do you think they had to say?
What is the truth? What was the seismic readings recorded?
