 As a result, in the 1990s, the FAA began conducting research on new technology to rapidly stop aircraft in less than in the event of a runway overrun.The engineered materials arrestor system (EMAS) was developed as a high energy absorbing material that could be installed as a surface beyond the end of runways, which was designed to collapse under the weight of an aircraft (absorbing energy and slowing the plane in the process) in the event of an overrun.EMAS was installed at LaGuardia Airport starting in 2005 and ending in 2015.
