Engineered Material Arresting System... airport runway paving blocks that slow planes down at the end of the runway (like a semi truck runoff on a freeway) in a safer way than the cables or berm method

The concept behind EMAS is fairly simple. Instead of putting asphalt before the thresholds of runways, the area is covered with a stretch of thousands of brittle, concrete-like blocks meant to collapse when the weight of an aircraft’s landing gear bears down on them. The plane’s gear continues to ride through the blocks, dramatically slowing the aircraft’s speed in a very short distance. The technology is especially relevant for airports with short runways and limited overrun areas.
