Passengers on a Southwest Airlines jet described a jarring drop on a flight from Hollywood Burbank Airport to Las Vegas that injured two flight attendants.

After departing from Burbank, traffic alerts required a Southwest Airlines flight crew on a Las Vegas-bound plane to "climb and descend to comply with the alerts," according to an airline representative.

The flight, bound for Las Vegas, plunged 475 feet from an altitude of 14,100 feet, according to flight tracking data
