Airport fire fighters reported their initial information indicated the aircraft had experienced a catastrophic electrical failure and the loss of cabin pressure, the electrical problems turned out minor later on.
The airline confirmed the aircraft diverted to San Jose due to a serious electrical problem. The aircraft has been removed from service and will not be permitted to re-enter service before a very detailed examination has identified the cause of the electrical issue.
The airline subsequently added that a malfunction of the air/ground switch, indicating that the aircraft was on the ground although enroute, caused the loss of cabin pressure and several systems including autoflight systems to drop offline. The passenger oxygen masks did not need to deploy.
