1. An aircraft wall assembly, comprising:
a panel comprising a ballistic protection layer configured to deform to absorb energy during a projectile impact; and
a barrier;
wherein the ballistic protection layer comprises a constrained portion, wherein deformation of the ballistic protection layer at the constrained portion is constrained such that the energy absorbed by the constrained portion during the projectile impact is reduced,
wherein the barrier is configured to deflect projectile material that passes through the constrained portion of the panel during the projectile impact.
