Observation

An engineering team mapped interior damage consistent with a large-aircraft mass trajectory through the Pentagon.

Interpretation

Supports AA77-impact against H014. Photographs of a façade hole are not the whole damage volume.

Source text

OBSERVATION: Civil engineers documented a continuous damage trail through three rings of the Pentagon consistent with a large aircraft. Engine-mass and landing-gear components were reported recovered.

The small-hole / missile argument is a photographic interpretation of the entry façade that does not address the interior column path.
