The man who crashed through a security checkpoint Thursday at New York's John F. Kennedy International Airport remains at large, nearly 24 hours after the incident.

Transportation Security Administration officials searched in vain for the man, who threw one of the world's largest travel hubs into chaos, on flights that landed in Fort Lauderdale, Orlando, Palm Beach, Salt
Lake City and San Diego.
The five flights were singled out because they shut their doors and began takeoff just after the security breach was announced at JFK, TSA spokesman Christopher White said.
"No specific intelligence indicat[ed] the suspect was on board one of the flights," TSA White told the Associated Press. "But there was the small likelihood that the individual could have gotten on a flight."
Meanwhile, a man was shot and killed in the airport's parking lot early this morning. "Police are still searching for the gunman," reports Newsday.
And travelers continued to lash out at Delta Air Lines employees, who sent JFK's terminal #3 into a near-riot yesterday, after announcing that planes would be taking off immediately -- despite a thousand or more fliers being stuck behind security checkpoints.
"After waiting with the mob at the Delta for two hours and being told that all flights would be held, we were told that all flights were departing on time with or without their passengers," one traveler reports in the comments here. "The
Delta attendants at check-in were uninformed, uninterested, unhelpful, and disdainful of the passengers."
"Hundreds of us were forced to stand outside in the freezing cold and wind for nearly an hour... with no explanation or information. This was especially awful for all of the families who had small children and elderly people. No attention was given to all of the people waiting and wondering what was going on," another flier tells our sister blog, 27BStroke6.
