If the internal supporting columns had collapsed upon impact, he says, the connection points would show cracks, because the damage would have been done while the steel was cold. Instead, he describes the connections as being smoothly warped: "If you remember the Salvador Dali paintings with the clocks that are kind of melted -- it's kind of like that. That could only happen if you get steel yellow hot or white hot -- perhaps around 2,000 degrees." -Abolhassan Astaneh

"The impact did nothing to this building" -CNN

"So now we know, the column did not fail, it was the failure of the floor in most cases" -Wired
