So if the main structural support is knocked over, and the added heat weakens the rest, it would be normal to look like a controlled destruction because both work the same way in this particular case.
The New York Times article (link in my first post) makes no mention of the supposed missing corner but does talk about a beam giving way on the 10th floor. In any case, we're not going to convince each other by pretending to be architects and engineers, so here's a quote from a real architect and engineer from the end of the above article:

Within moments after the news conference ended, leaders of a group called Architects and Engineers for 9/11 Truth held their own telephone conference briefing, dismissing the investigation as flawed.
“How much longer do we have to endure the coverup of how Building 7 was destroyed?” said Richard Gage, a California architect and leader of the group.
Told of the doubts, Dr. Sunder said he could not explain why the skepticism would not die.
“I am really not a psychologist,” he said. “Our job was to come up with the best science.”
