A new aviation-safety device, designed to terminate runway overruns, has been installed at New York's JFK International Airport. The arrester system, located at the end of Runway 4R-22L, uses as many as 2,000 2.4 x 1.2m foam blocks of aerated, cellular cement to stop a wide body aircraft. JFK is the first site for the installation, developed jointly by the US Federal Aviation Administration and the Port Authority of New York and New Jersey. The safety device will cost $2.6 million to install on Runway 4R, and up to five more are planned.
