"A large piece of wreckage was found in the [Pentagon] entry hole; but the public was kept from closely observing what appears to be a sheared-off piece of wing from a much smaller jet than a Boeing 757.
A group of military personnel and federal officials in suits tightly covered the piece of wreckage with a blue tarp and carried it away to a waiting truck"
Here's the photo accompanying this story.
It's to be found on many other sites, too, although without the extra details that are added here. So is this a plausible story? We don't think so, for the following reasons.
#1, the idea that a large piece of wing will be found after hitting the reinforced Pentagon wall, at 500 mph, seems unlikely. Especially so large that you can readily identify it as something else.
#2, even if that is possible, take a look at the photo again. If these men are "carrying" something then it doesn't look like it weighs anything at all: some are using one arm only, others just vaguely steering, no-one looks like they're breaking a sweat.
#3, note that there are no references here for the important details. Who says it was a piece of wreckage? Who identified it as from a wing? Flocco doesn't say -- we're just supposed to believe it.
#4, the photograph itself proves nothing. We don't know when it was take, or where. The conspiracy sites who use this image like to say it shows something being taken away, but never have any explanation of how they know that, either. Why can it not be something being brought to the Pentagon?
#5, there are alternative candidates for lightweight objects being bought to the Pentagon, too. Take a look at this Pentagon cleanup photo, for instance -- the grounds are full of tents, and there's a few blue tarpaulins around, too. See http://www.defenselink.mil/photos/Sep2001/010914-F-8006R-005.html for the original.
And take a look at this closer image. Note the blue ribbed look, white innards, a close match with our original photo.
#6, we found a version of the original photo that contained the URL http://jccc.afis.osd.mil/images/sres.pl?Lbox_cap=347704&dir=Photo&vn=&ttl=010911-F-3050V-020&ref=defenselink in its Comments field (right-click in Windows, select Properties > Advanced). This site is restricted so we can't confirm it's correct, but if so it raises another question. If this image is depicting some key moment of evidence destruction, then would the conspirators take a photograph, then preserve it forever online? Doesn't make a lot of sense to us.
None of this can prove there isn't something suspicious happening here, but then proving a negative is always tricky. What we can say is that the "carrying away a wing" claim seems unlikely for several reasons, and there’s a distinct lack of any evidence to support it.
