I'm not going to really speculate on it because afterall the behavior after impact is going to be very unpredictable depending on each individual impact in the buildings the engines would have made but at 600mph or so and the massiveness of the engines would have made for a very solid projectile.

*Apology for the 16' thing. I should have been more specific. The firefighters measured it to be roughly 16' WIDE, not tall. It was only about 11' tall. Good eye. One thing; it wasn't going 600 mph. This huge engine that punched the hole burned to a crisp? Why so little fire damage where it would have burned to nothing?

Even still the fire damage to the building is rather extensive but it was left standing because it didn't have a steel frame that was holding the building up.
I really can't see how this is even an issue.

The WTC had fire sprinklers (the same as the Pentagon has). So the fire supression system prevented any serious fire damage (like frame melting), but the fire was easily able to melt away almost the whole plane? Also, the Pentagon does have steel reinforcement.
The Pentagon is constructed with 42,000 40 cm. (15") square steel reinforced concrete pillars. The graphics below, provided by the DoD, shows the extent of the damage from the attack on 9/11 as destroyed pillars. By their count, there were 32 pillars destroyed, and a lesser number stripped to their steel reinforced core. What is astonishing is the fact that the destroyed pillars form an almost perfectly straight line on a 45 degree angle. Nothing in the chaos of the disintegration of a soft shelled mass of fluid like an airliner hitting a stone, concrete and brick wall with steel reinforced load bearing pillars, would lead you to expect an almost perfectly linear path of destruction. A plane is like a sausage skin: it doesn't have much strength and virtually crumbles on impact.
The damage to the interior is too deep and too collimated to be from the liquid fuel of an airliner.
Again, thank you for posting honestly and respectfully.
