A plane traveling from California to Washington State was forced to make an emergency landing in San Jose recently because of a malfunction in the electrical system. The Alaska Airlines flight — bound for Seattle, Washington, from Ontario, California – had just taken off when the plane’s air to ground sensor failed, requiring the pilots to fly the plane manually when the auto throttle became disconnected among numerous other electrical system malfunctions.
The plane’s pilots announced an emergency situation, which required them to depressurize the plane themselves, but the plane’s oxygen masks – designed to deploy automatically when the cabin begins to lose air pressure — never dropped from their overhead storage compartments. Passengers in the plane report overhearing flight attendants commenting to one another about the severity of the situation before the cabin’s backup pressurization system became automatically activated. The flight landed safely in San Jose with no reported injuries.
