Default Pentagon hole NOT SOLELY by 757

wrote:

How do you create a nice clean hole in a reinforced concrete wall? with
an explosive shape charge. An explosive shape charge, or cutting charge
is used in various military warhead devices. You design the geometry of
the explosive charge so that you create a focused line of energy.


And, they actually were able to hit the exact spot in the wall with a
757 with pinpoint accuracy.
