Abstract
A system for arresting movement of an aircraft traveling off the end of a runway at high speeds. Rigid, friable, fire resistant foam boards, preferably phenolic foam, are connected to form a panel, and a plurality of layers comprised of stacked panels are adhered to a base surface. The panels are formed from unfaced foam boards, the compressive strength of the stack of boards being less than the force exerted by the landing gear of the aircraft to allow the boards to be crushed by the landing gear.
