A record 70.6 million passengers a year now pass through Los Angeles International Airport as it undergoes a multibillion-dollar "world class" modernization.
Passenger terminals, like Tom Bradley International, are being remodeled with upscale shopping and dining. Runways are being refurbished, and public transit is finally on the way.
But high up in the control tower of the nation's second-busiest airport, the outlook is not so good. Air traffic controllers are working longer and harder than ever to safely handle the enormous volume of aircraft that arrives and departs at this prominent West Coast gateway.
