A Boeing 737 jet arriving from Guantanamo Bay reportedly carrying 142 passengers and crew members went off the runway into the St. Johns River in Jacksonville, Fla., on Friday evening.

stupid question , but
its a fact that aircraft can overshoot runways
why not have a " sand trap " at the end of runways that have a hazardous overshoot ??
EMAS is essentially a rectangular bed of 2,000 to 4,000 collapsible cubes glued in place at the end of a runway, nearly level with the ground. As a plane careens into the cubes, the cubes break apart. Friction between the cubes and the plane's wheels ultimately slows the plane to a stop. The system can safely stop a Boeing 737 traveling at 65 miles per hour in fewer than 300 feet.
