Is the new double-decker Airbus vulnerable to sudden drops in cabin pressure? That’s the kind of problem suspected in this summer’s crash of a Helios Airways plane that killed all 121 people on board.
The former chief engineer for the company that designed the microchips controlling the motors that runs the pressure valves thinks so. The company, TTTech Computertechnik AG, of Vienna, fired him for going public with his concerns. For good measure, it has sued him in both civil and criminal court. Austria has no laws to protect whistleblowers.
