History

Historical Context

In 1991 a USAir 737 struck SkyWest’s Metroliner at LAX, killing 23 and injuring 12. The NTSB blamed tower procedural flaws, prompting the FAA to mandate runway segregation and, after the July 1996 collision, a $150 million rollout of Airport Surface Detection Equipment-Model X (ASDE-X). The incident follows earlier incursions such as the 1977 Tenerife disaster, underscoring a long-standing safety challenge.
