Engineered Material Arresting System

Material science is all about choosing the right material for the right job. And if we can't find the right material, we can always modify it. Here we see a solution to the problem of airport runway overruns.

The requirements - as mentioned in the video - are things like fuel fire resistance, low cost, access to emergency vehicles, ability to withstand jet blast, limited damage to the aircraft, replaceability. and durability through freeze/thaw cycles. The solution given here is a composite of cement designed to slow the aircraft as the Emergency Material Arresting System (EMAS) is destroyed.
