In this clip is the live report of one of the first on the scene reporters, CNN's Jamie Mcintyre.
The transcript is as follows:
"From my close-up inspection, there's no evidence of a plane having crashed anywhere near the Pentagon.
"The only site, is the actual side of the building that's crashed in, and as I said, the only pieces left that you can see are small enough
that you pick up in your hand. There are no large tail sections, wing sections, fuselage, nothing like that anywhere around which would indicate that the entire plane crashed into the side of the Pentagon and then caused the side to collapse.
"Even though if you look at the pictures of the Pentagon you see that the floors have all collapsed, that didn't happenm immediately. It
wasn't until almost about 45 minutes later that the structure was weakened enough that all of the floors collapsed."
