Alaska Airlines Flight Loses Cabin Pressure in ‘Catastrophic Electrical Failure’
Alaska Flight 539 from Ontario, Calif., made an emergency decent from 28,000 ft to 8,000 ft and diverted to San Jose, The Aviation Herald reported. First responders were told it was the result of a “catastrophic electrical failure.”
The plane’s transponder also failed, making it invisible to air traffic controllers.
While no one was injured, the plane is expected to remain out of service until the root of the failure can be determined.
