Moment of shock shortly after takeoff: An airplane suddenly begins to descend over California.

Two flight attendants were injured when a US Southwest Airlines passenger plane suddenly descended in California. The crew changed course on Friday (local time) in response to a warning that another aircraft was nearby, the US Federal Aviation Administration (FAA) said. The incident is under investigation.

According to Flightradar24, the Boeing 737 temporarily descended by approximately 150 meters after a scheduled climb before regaining altitude. According to CNN, a fighter jet was nearby, which may have triggered the alarm. A spokesperson for Hollywood Burbank Airport stated, according to the New York Times, that there was no evidence of a near-collision in the airspace above the airport.

According to the airline, the plane continued its flight from Hollywood Burbank Airport in Southern California to Las Vegas, Nevada. It landed there without incident. The airline stated that it was not aware of any injured passengers, but two flight attendants were being treated for injuries.
