Newton is of course right and the advisors of Condoleeza and GWB are wrong. Unfortunately Condo and GWB have never heard of Newton. I wonder about NIST. Hasn't it heard about Newton?
Yes, the forces are equal. One up, the other down according Newton. Equilibrium. Without it you would fly away.
And you are then 100% right. The upper block, the sheet of glass, and the lower structure, the bowling ball, experience equal forces at contact of any type.
And it means, according you, that the sheet of glass, the upper block, breaks. and the bowling ball, the lower structure, is hardly affected at contact.
It is not so simple re WTC1, but you are on the right track.
Or did I misunderstand? The upper block was the bowling ball and the lower structure of WTC1 was a sheet of glass?
That is Bazant, Seffen, NIST P0S! You do not believe that, do you? The plane hit the tower and released a bowling ball that dropped on a sheet of glass.
That is ridiculous. But NIST wants you to believe it.
