There was a building right next to the towers that wasn't hit, yet it came down like in a demolition.
And your point is?
Years ago while overseas I was given a choice of 2 new assignments - 1 was in Oklahoma, and the other was in Georgia. I went home to think about it, and that night my wife and I turned on the TV...to see that Oklahoma had been hit by a record 100 (one hundred) tornados in 1 day.
Right outside the front gate of the base where I was offered an assignment was what was left of the local housing community. As far as you could se there was devastation - every house ripped from the foundation and scattered like confetti....EXCEPT FOR ONE! That house was untouched - complete with running water and electricity thanks to a generator.
Explain that one. (Rhetorical)
If I am not mistaken, the building you are talking about that was untouched next to the Twin Towers (across the street?) was a CHURCH. I visited the church when I went there for a visit before volunteering and deploying right after the attack Almost every other building nearby received some type of damage....but the church was almost completely untouched.
As I said, I don't waste a lot of time trying to wrap my head around why one thing was spared and why one was not. To me, the fact that 3,000 Americans were murdered makes that inconsequential.
