If only the world were as black and white...
If people did their research they would find that, in the 12 months prior to the Helios accident, other aircraft got airborne with the system in MAN and the crew did not spot it. Other crews failed to diagnose systems problems related to pressurization. Other crews misdiagnosed the warning horn. Other crews failed to don their masks. It happens every year and will continue to happen. Helios is no more than an extreme example of a not uncommon event.
Hindsight is a wonderful thing and the court action is just a social system wanting to find a scapegoat to explain an irrational tragedy. I blame God. If she hadn't invented gravity aircraft wouldn't crash.
