Collision on Tokyo Runway Results in Five Deaths

Aviation safety 'Swiss cheese' model suggests series of small errors led to fatal crash.

An Airbus A350 from Japan Airlines collided with a smaller Dash-8 turboprop from the Japanese Coast Guard on the runway at Tokyo's Haneda Airport, resulting in five deaths from the Coast Guard plane.
The Dash-8 pilot did not have clearance to enter the active runway, but believed he had clearance to take off.
The 'Swiss cheese' model of aviation safety suggests that the crash was likely caused by a series of smaller errors, including potential pilot fatigue, malfunctioning runway lights, and the aftermath of an earthquake.
Despite the collision, all 379 passengers and crew aboard the A350 jetliner survived, with the evacuation taking about 18 minutes using only three of the eight emergency exit doors.
Runway incursions, such as this one, are a significant challenge in aviation safety, with data indicating that almost 60% of all accidents are related to runway safety.
