I have recently listened to a program shown on AL Jazeera tv concerning the cover-up of faulty parts manufacturing for Boeing737-800s [I think that was the model]. Witnesses to this were initially two Boeing employees who decided to 'whistle blow' after a routine visit to the company-Ducommon- the manufacturer of the parts in question. Since then other Boeing aircraft assemblers have apparently backed up these accusations, the FAA has been involved as has the US Department Of Justice.
What is all this about ?
Is there any truth in what this program seems to be suggesting ?
