Alarms sounded in the cockpit of a Southwest Airlines jet shortly after taking off from Hollywood Burbank airport near Los Angeles on Friday, prompting evasive maneuvers, the airline said in a statement.

The Southwest Boeing 737 departed just before noon local time on Friday for a scheduled flight to Las Vegas. Six minutes after takeoff, a privately owned Hawker Hunter fighter jet crossed less than two miles in front of the Southwest plane, passing within a few hundred feet of the same altitude, according to flight tracking site Flightradar24.

A Southwest Airlines flight plunged mid-air on Friday to avoid colliding with another aircraft while en route to Las Vegas, injuring two flight attendants, as passengers described flying out of their seats.
