How many buildings collapsed on 9/11 in New York?

Question

How many buildings collapsed? I am looking for a number.

Read the question carefully:

"on 9/11" means only on September 11, 2001, how many buildings collapsed. Other buildings may have been brought down in later days, do not include these in your answer.

"in New York", that means only in New York City, how many buildings collapsed. Other cities may have had buildings collapse on 9/11, do not include these in your answer.

Answer 1

There were three- the two hit by a plane and one that just burned to the ground without any reason given- But all three were took down by demolitions, which can be plainly heard on the tapes.

Answer 2

Three buildings officially "collapsed", according to government reports, on 9/11.  They were WTC1 and WTC2, which were both allegedly hit by airliners, and WTC7 which was not.

As far as I am personally concerned though, NONE of them collapsed.  WTC1 and WTC2 more like "vaporized".  WTC7 appears to have come down by controlled demolition.

Maybe someday our government will tell us the truth about the crimes of 9/11.  We can only hope.
