If you ask me, too many embarassing errors in this story to be taken serious. Dutch own Airbus? A380 flying as high as a business jet (comparison to the Payne Stewart case). Even if an outflow valve fails, there are still the PSU (oxygen generators), working completly undependent. The list goes on.
This is just a scam, based on half wisdom and based on fear in the aftermathes of the Helios crash.
