Photos Of Flt 77 Wreckage
Inside The PentagonThe recent Pentagon crash discussion on Rense.com has almost entirely focused on photos of plane debris on the lawn. Since most of the plane reportedly entered the building, we should also look for images of debris inside the building. Unfortunately, such images are very hard to come by since: (1) Much of the debris was burned and torn beyond recognition, (2) Most FEMA photos in the public domain were taken on 9/14/01, after much of the debris was cleared out of the building, (3) Most other photos remain in the private hands of investigators, rescue workers, and others who were inside the building. Many images are officially classified. The following article attempts to bring together all known images sent to me or in the public domain that show aircraft debris inside the Pentagon. The images were either found online or sent to me by recovery workers to be used with permission. First, we shall examine witness accounts of plane debris inside the Pentagon. These were given by recovery workers, firefighters, engineers, and Pentagon officials. Their statements help in interpreting the various photos taken inside the building.
Most of the heaped scrap is unrecognizable, but there are two pieces of metal bearing yellow-green primer which were not burned thoroughly. Charles Burkhammer similarly noted small lime-green pieces of aircraft interior.
Resting next to another pillar is another section of lime-green material bearing clear rivet lines (photographed by
FEMA's Jocelyn Augustino):
This photo of engine remains was taken in either D or C-ring by VATF-1 workers. The large circular piece in the middle appears to be the diffusor section of the compressor, though this is not known for certain. Note the torn column nettings on the right. On the left is an obvious piece of yellow-primed aircraft fuselage bearing rivet holes and a twisted silver metal piece next to it.
: the following photo shows a landing gear found inside C-ring near the punchout hole. Note how completely charred the rest of the debris was.

In the heap of debris next to the hole lies an airliner wheel hub from one of the landing gears (as shown on TLC's "Pentagon Under Fire," aired 9/11/02):

The following photo, which ironically enough graced the cover of T. Meyssan's "Pentagate" book, shows both the fuselage fragment and the wheel hub:
