Care to share where you got this false information from? You should fire them because they have no idea what they're talking about.
A 1200-page analysis on the towers was released on February 3, 1964 and it states:
The buildings have been investigated and found to be safe in an assumed collision with a large jet airliner (Boeing 707—DC 8) traveling at
600 miles per hour. Analysis indicates that such collision would result in only local damage which could not cause collapse or
substantial damage to the building and would not endanger the lives and safety of occupants not in the immediate area of impact.
The above emphasis is mine. That paper explained exactly what happened on 9/11. Had the towers not been brought down with explosives, they would still
be standing today.
John Skilling, head structural engineer for the World Trade Center:
Our analysis indicated the biggest problem would be the fact that all the fuel (from the airplane) would dump into the building. There would be a
horrendous fire. A lot of people would be killed. The building structure would still be there.
Kinda like this building structure that was still there after burning for almost 24-hours straight, unlike the 56 minutes in the south tower:
Notice there was only a partial collapse in the above structure from the intense heat and from burning so long. 56 minutes in the south tower vs.
24-hours? Puhlease.
Frank DeMartini, WTC construction manager:
When Frank DeMartini says "fully loaded", that means fully fueled also.
As far as your original quote that the buildings weren't designed to withstand that size of plane:
The 707 and 767 are close in size and weight. The 707 (which is what the buildings were designed to withstand) flies faster than a 767 which impacted
the buildings on 9/11. The faster speed of the 707 makes up for the slightly lower weight.
Since the 707 and 767 are very comparable, you could say that the buildings were designed to withstand 767's as well. Never let anybody tell you
those buildings weren't designed to withstand the impact of 767's like we were shown on 9/11. They are absolutely wrong.

All they did was weaken the columns on the floor where they wanted the building to collapse.
They weakened every single column on the whole entire floor. Not 35 columns out of 240 perimeter columns, or 2-3 out of 47 core columns. And not to
mention only on a single side of the WTC's, not across the whole entire floor.
That equates to about 14% damaged columns in a WTC tower compared to 100% damaged columns in that demolition in the OP. Big difference there.
