A very complex story from 15 years ago. There haven’t been many depressurisation incidents on the A380 and like they say in the article, why would they cover this up? Maybe the whistleblower really is just a disgruntled employee.
you will never know if the lack of pressurization issues was because their plan was fine or caused by changes thanks to his campaign. hindsight is 20/20.
the fact that they took that route is the problem.
