A Southwest Airline jet heading to Las Vegas from Southern California took a dramatic plunge shortly after takeoff Friday in response to an alert about a nearby plane, sending some passengers flying out of their seats and injuring two flight attendants.

Passengers said the pilot of a Southwest Airlines flight had to "dive aggressively" in order to avoid a midair collision over Burbank.

Two attendants were hurt on Friday during an emergency maneuver on a Southwest flight departing Hollywood Burbank Airport.
