Looking for the safest place to land in America? Do not head to Los Angeles, it has the most dangerous runway system in America.

It’s not a record you want to brag about: Los Angeles International Airport and two others nearby have the worst runway safety records recently among the nation’s busiest airports, a review of federal aviation data shows.

Federal officials are most concerned by the situation at bustling LAX, where commercial jets have come perilously close to crashing at least twice since 1999, the first year of data reviewed by The Associated Press.

The problem persists because, despite millions spent to reduce violations known as runway incursions, LAX’s airfield has built-in flaws: It’s too tightly packed, and arriving aircraft must cross runways used for takeoffs.

Runway incursions occur when a plane or vehicle on the ground gets too close to a plane that is landing or taking off. via CNN
