The systems at New York’s LaGuardia Airport intended to prevent collisions on the runway recently failed when an Air Canada flight landed and collided with a fire truck. The ongoing investigation by the National Transportation Safety Board (NTSB) is focused on why the Airport Surface Detection System (ASDE-X) did not trigger an alarm in this critical moment, despite its previous track record of averting similar accidents. This incident resulted in the tragic loss of both pilots and injuries to many. Experts are examining several contributing factors, including the lack of transponders on the fire truck and the chaotic situation due to emergency calls nearby. Although ASDE-X is one of many layers of safety measures, this incident highlights the need for improvements in standardized safety protocols at airports.
