now I've supervised mechanics putting together turboprop, turboshaft and turbofan engines and APU's, and I have yet to see a part that looks like the one found in the wreckage which wasn't recognizable by reps of R&R and P&W
Even so, from the text of the very first link:
There have been some people who claim that a Global Hawk was what hit the Pentagon. Here is what John W. Brown, spokesman for Rolls Royce (Indianapolis), had to say about the part in the photo above "It is not a part from any Rolls Royce engine that I'm familiar with, and certainly not the AE 3007H made here in Indy." (Of course it wouldn't be anything he's familiar with, it's a powerplant made by Honeywell.) The AE 3007 engines are used in small commuter jets such as the Cessna Citation; the AE 3007H is also used in the military's unmanned aircraft, the Global Hawk. The Global Hawk is manufactured by Northrop Grumman's subsidiary Ryan Aeronautical, which it acquired from Teledyne, Inc. in July 1999. A detailed view of what the turbofan that powers the Global Hawk looks like - I'm sure you can see it's too small to be anything in the pictures contained here or anywhere else in the Pentagon crash evidence. Also visible in this photo, one of the 757's blue passenger seats to the left of the turbine, and possibly a 2nd seat above the other seat.
DoDo: How many planes crashing into massive buildings at near maximum speed have been part of your professional experience? manon: what makes you so eminently qualified to judge events? manon: no answer. Colman: You want an answer in twelve minutes??? manon: ok, you know something about engineering and/or aircraft? Colman: Me? Shit no. But I don't get all cranky if I don't get a response within twelve minutes. ...later, on a parallel thread... DoDo: 12 minutes passed.
...later, on a parallel thread...
DoDo: 12 minutes passed.
If I may comment this meta-discussion, I don't see my problems with manon's debating style explained by Jérôme's provocation, nor do I think mentioning that he won't follow Kos's policy is the same as "bringing up" Kos's banning policy, even though I disagreed with that initial comment by Jérôme and saw it as provocative (and implied so in a reply, which to complicate things was in turn taken as an insult by manon). *Lunatic*, n. One whose delusions are out of fashion.
manon: what makes you so eminently qualified to judge events? blind faith or something more substantial?
6 mins later...
manon: no answer. I guess blind faith. And I thought we were all hip people who didn't put much faith in blind faith.
Those are arrogant, belittling comments that were not justified (by what you want to say about Jerome or by anyhting else). Colman stepped in with his twelve minutes comment to wisecrack... OK, it didn't work... and suggest manon was overdoing it.
Later, DoDo explained that he didn't reply instantaneously because he was looking for data. And when manon didn't reply to a question of his, he pulled out the "twelve minutes" clause. The troll rating for that was obviously ridiculous.
BTW, I asked manon three-quarters of an hour ago what she meant by "open for business". I mean to get an answer.
What, by me now? Wowee...
Let me point out, manon, that you have distributed troll ratings, while no one, afaik (if I'm wrong forgive me) has troll-rated you. And you have slung around some pretty high-handed comments about other people's capacities and qualifications. I don't think you are justified in passing yourself off as a victim.
Bonus: more metal parts close-ups for you:
(Even more at this Italian page.) *Lunatic*, n. One whose delusions are out of fashion.
A torn gasket with a fuel filter still attached?
And some unknown but rather small parts of the aircraft?
And would they have been spread out on the grass by the suitcase carriers before whatever made the impact on the Pentagon, or after?

I'm not trying to push some conspiracy, it's just something that has always been sitting there with a questionmark hovering over it, and I've never found anyone who had enough technical knowledge to explain it to me. Any idiot can face a crisis - it's day to day living that wears you out.
the parts are pretty heavy, mechanically fitted together, wired into place (every bolt has to have wiring around it so it doesn't loosen) and many of the parts are designed to withstand extremely high temperatures
the Pentagon is reinforced so it would not replicate the same conditions, but there would be some similarities to your incident
maybe if you could give us some more details of what you remember about it?
In Dodo's links you'll find those pictures of the damages on the outer part of the building. The structural damages were mostly at the ground floor and is consistent with the flight path and height level (in fact the plane must have been on a an air cushion effect, "effet de sol" in french).
One of them, left wing, chunked out a bit of concrete railing and the right one hit the generator (two structures at less then 1m and 3m high respectively) and went inside (picture of one engine inside the wrecked building) through the ground floor part of the facade.
Not surprisingly, the pictures show that posts and beams are damaged much further then the central big hole... (the famed wing problem)!
The Pentagone building shape and built technique had the same effect (my feeling) then the multiple layers of plastic sheets used to stop a bullet in forensic tests... The shape charge effect of such a plane at such a velocity would have otherwise reached the central courtyard. While it seems that only two holes were blown up on that side (either perpendicular corridors, or part of the engines)!
I would agree with some that the chances to hit the target, flying so low and in such a short distance to maneuver and align the plane is really hard to achieve even for a trained fighter pilot !
