And, for any who might doubt that the bombing of the Murrah Federal Building was much more than publicly acknowledged, I would invite you to look at the following:
To set the stage, BG Benton Partin was the former Commander, US Air Force Armament Laboratory, and widely considered to be the “father of smart weapons technology”, i.e., no “conspiracy theorist” but a bona fide expert on physics and the effects of explosives.

Both of the above documents are a matter of public record.
BG Partin ignores the strong possibility that a shape charge geometry was used to focus the blast toward the building, instead of a simple undifferentiated blast, which Partin assumes was the case.
We know that nitromethane was purchased for the bomb. It significantly increases the detonation velocity of ANFO.
You can get reflected blast waves that can reinforce the blast in some areas and cancel part of the effect in others.
I taught blasting for a semester when I was a grad student in mining engineering.
I have a masters degree in mining engineering.
Bento Partin has a Batchelor of Science degree in chemical engineering and a Masters in Aeronautical Engineering.
I worked in Army RDT&E for 30 years.
Explosions are not necessarily uniform homogeneous events.
Here is an explanation of focusing the explosive effect toward the building. It was talked about by McVeigh.
“Bradley said a triangular-shaped placement of barrels containing explosives could have been used to focus the blast toward the federal building - particularly if there was an empty barrel or gap in the triangle on the side facing the structure.
Military and civilian blasters have for many years used the same principle to focus energy using linear- or conical-shaped charges, he said. They even have a name for it: the “Munroe effect. “ Bradley said he would like to refute one statement that has appeared in newspapers.”
