Investigators say that a private jet came within 100 feet of crashing into a Southwest Airlines plane on a runway in San Diego two years ago because the air traffic controllers in the tower got distracted. The National Transportation Safety Board issued its final report Tuesday on the incident that happened in August 2023. Both the controller directing those planes and the supervisor made bad choices that day that took their attention away from the landing, the NTSB said. Another factor that contributed to the planes coming so close is that the controller’s supervisor in the tower was also distracted. The NTSB said the supervisor was in the middle of troubleshooting a problem with a printer the controllers use.
