TESLA, the Pentagon was a reinforced concrete structure if not huge blocks of stone and concrete. Only the fuselage core bore a hole through the wall.
The WTC was designed with structural steel-frame, the interior comprising 95% air as they say. It's curtain wall was not solid. Therefore, the planes created a hole of their silhouette for the impact point.
Yes and the towers were meant to withstand a large crash from a plane.
As you linked to various sites, I'll do the same now.

Airplane impact tests conducted by WTC structural engineers during the design of the Twin Towers used the Boeing 707, which was one of the largest passenger jets in the world at the time. The results of the test, carried out early in 1964, calculated that the towers would handle the impact of a 707 traveling at 600 mph without collapsing.
Even though the two Boeing 767 aircraft that were said to be used in the 9/11 attacks were slightly larger than the 707, technical comparisons show that the 707 has more destructive force at cruising speed. The following analysis was compiled by 911research.net:
The maximum takeoff weight for a Boeing 707-320B is 336,000 pounds.
The maximum takeoff weight for a Boeing 767-200ER is 395,000 pounds.
The wingspan of a Boeing 707 is 146 feet.
The wingspan of a Boeing 767 is 156 feet.
The length of a Boeing 707 is 153 feet.
The length of a Boeing 767 is 159 feet.
The Boeing 707 could carry 23,000 gallons of fuel.
The Boeing 767 could carry 23,980 gallons of fuel.
The cruise speed of a Boeing 707 is 607 mph = 890 ft/s,
The cruise speed of a Boeing 767 is 530 mph = 777 ft/s.
So, the Boeing 707 and 767 (9/11 planes) are very similar aircraft, with the main differences being that the 767 is slightly heavier and the 707 is faster.
So the planes that hit WTC 1/2 were 10 wider, 6 feet longer, 980 more gallons of fuel and the MODERN Boeing was slower.
So the towers would still take the impact just fine, but somehow the planes just etched itself into the building and a comparison by simply saying a "structural-steel frame" to dismiss it as though it were nothing compared to the Pentagon isn't fair.
Question though, any videos of the Pentagon attacks? I mean, surely one of the 80+ cameras around caught something?
Another question, if the fuselage went through the Pentagon, what happened to the wings? Debris etc? Pictures? Videos?
Okay, a third great question,
why is the grass not burned up and scorched?
This is great stuff, we learn more as we go along, isn't this fun?
