“Mad Men” was in the process of filming an episode at Los Angeles International Airport Friday morning when a deadly shooting incident occurred at the travel hub, according to tweets from a production staffer.

Plenty of other bizzers were caught up in the shooting drama and the traffic snarl that ensued around 9:30 a.m. PT as the airport was evacuated while law enforcement hunted for the shooter.

Dustin Woods, a key grip on the AMC’s “Mad Men,” tweeted that the series was filming in American Airlines’ Terminal 4 at LAX, one terminal away from where shots were fired at approximately 9:20 a.m. PT.

Woods tweeted to TV Guide’s Michael Schneider that the show on which he was in production was “Mad Men,” noting that it was the program’s first day back lensing.

AMC declined to comment.

CBS senior exec VP Kelly Kahl was on his way to the airport for a flight when the lockdown occurred. He was unable to get into LAX and wound up re-routing his travel plans through Long Beach Airport. Amid the chaos, Kahl telephoned KCBS-TV Los Angeles to provide an on-the-scene report.

Actor James Franco was stuck sitting on the ground in a plane when the shooting took place, which he chronicled via Instagram.

Grant Imahara and Tory Belleci, of Discovery Channel’s “Mythbusters” series, were in Terminal 3 where the shooting occurred. Both were on their way to Delaware for the filming of Discovery’s popular holiday special “Punkin Chunkin.”

“Grant and Tory are safe and being rerouted. Our thoughts are with all those affected by today’s tragedy and our gratitude goes out to the members of the LAPD, Airport Police, TSA, and Virgin America staff for restoring safety to the scene,” Discovery and Science Channel said in a statement.

Late Friday, the FBI identified the shooter as Paul Ciancia, 23, of Los Angeles.

The deadly incident continued to reverberate for thousands of travelers Friday as more than 100 flights were delayed or canceled because of the disruption.
