Abstract

An aircraft runway safety area for slowing an aircraft that has overrun a runway, including a brittle, nondeformable material for arresting the travel of an aircraft without catastrophically damaging the aircraft, the nondeformable material being configured to crush upon being contacted by the aircraft to effect arrest, and comprising incompressible material in the form of one or more foamed glass bodies, each respective body having a top surface, a bottom surface and oppositely disposed side surfaces, and a frangible matrix encasing the one or more foamed glass bodies, the frangible matrix fabricated to protect the incompressible material and having a breaking strength sufficient to readily break without subverting the arrestment characteristics of the incompressible material. The frangible matrix is different from the incompressible material.
