An investigation is underway into a plane crash that killed five people after an Amazon cargo plane overshot a runway and crashed into two vehicles. The National Transportation Safety Board is looking into the incident. A press conference was held, where the lack of a safety system at the airport was discussed.

The system, known as Engineered Material Arresting System, is designed to help stop planes that come in too fast at the end of a runway. The NTSB Chairwoman noted that the US has a safe aviation system, but tragedies are devastating when they occur. Over 70 airports in the country have this safety system in place.

Further details about the incident and investigation are available.
