A cargo plane crash has raised questions about airport safety features. The incident involved a 767 cargo plane that overshot a runway, slid a significant distance, and burst into flames. Engineered Materials Arresting Systems, or EMAS, are being discussed as a potential solution to prevent such crashes.

EMAS is a safety feature that uses crushable material to slow down an aircraft that overruns the pavement. This technology is used at more than 70 US airports, according to the Federal Aviation Administration. However, it is not used at the airport where the cargo plane crashed.

For more information on the incident and the role of EMAS, further details are available.
