Commercial aircraft use a diverse variety of jet engines. However a comparison
shows that jet engines currently in use have a much lower mass-to-volume and
mass-to-sectional-area ratio than the GE-J79, the jet engine used in the Phantom. As
an example Fig.
16.4
shows the jet engine of a Boeing 747. Using the established
sources it was determined that these engines are also not able to penetrate a 1.80 m
thick steel reinforced concrete such as those used in convoy containment. This case
is not seen as a particular threat potential for the containment but there is danger of
penetration in the case of thinner walls.
