I'd be only guessing about what made the hole, no point speculating. The landing gear was found though inside the Pentagon I know that.

I just provided audio evidence Goper 6, saw the plane NE bound descending before it crashed. If it was descending after the turn the plane could not be on a SW position for the 5 lightpoles to be knocked over.

neutronflux 757 plane was using a magnetic compass not a standard compass. It was calibrated for deviation. The compass dials would be showing an SW direction if that's where it was. Instead the compass was showing a NE path on 70 magnetic.

neutronflux Shear studs provide support to stop the floors and girders from buckling from fire damage.
NIST removed the shear studs on Column 79 and 44 to explain the collapse. Fires were not hot enough to cause buckling with the shear studs connected.

Pilgrum The plane heading was approximately 60 degrees NE this was it's true North course near Arlington. You can see that on the dials of the compass was fixed on the 60 degrees dial that's why the compass read 70 magnetic.
60 degrees + 10 coming from the NE= 70. Going West you subtract not add.
mark (a gauge or instrument) with a standard scale of readings.
correlate the readings of (an instrument) with those of a standard in order to check the instrument's accuracy.

neutronflux It based on the grid for Washington DC. Magnetic North is the field up around Greenland and Canada. If you heading North in the Washington area your heading North to Arlington!
True North is just the plane true course at the time it was 60 degrees.

Compass, magnetic and true course.
Calculates true, magnetic and compass direction(course, bearing) by given direction, magnetic declination and deviation.
