Operations at Los Angeles International Airport were returning to normal by this afternoon following yesterday's shooting that killed a TSA officer and closed parts of the airport. Terminal 3 has reopened, airport officials say. Thousands of fliers across the US were delayed after the attack; the prolonged shutdown at the nation's third-largest airport was particularly troublesome for those hoping to head to the East Coast or across the Pacific Ocean. About 1,550 flights with 167,000 passengers were affected, says an airport rep. Today, a flight-tracking expert tells the AP things are getting back to normal, with "no notable delays," though he says there have been 28 cancellations related to the shooting. Meanwhile, we're learning more about the accused shooter.
