LAS VEGAS (AP) — Passengers aboard a Southwest Airline jet that took a dramatic plunge to avoid an oncoming aircraft were told by the pilot that they nearly struck another plane before landing safely in Las Vegas.

A person on the flight said it “dove aggressively” and that people flew out of their seats. The flight landed safely at its destination, Las Vegas.

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 plane suddenly jolted shortly after takeover then felt like it was falling, said Stef Zamorano, who was flying to Las Vegas with her husband to celebrate his birthday.
