Have we ever heard from the Malaysian government that the cargo listing that they are refusing to identify because of "security" reasons was not in any way hazardous enough to be considered in bringing down this aircraft?
Yes, and I can vouch for that because I perform Quality Assurance testing on hardware, firmware, software.
If a vendor recalls a component that is in the field, it is our responsibility to take the necessary steps to revoke the item (s). If the part were to fail, and we did not do what the vendor asks, it is our fault.
IMO, it's the same thing with this case, if, in fact MH370 has a faulty component.
Respectfully, I am not sure that your answer matches the question asked.
What you said may well be true, however in the case of MH370, there has been NO recall.
All the public knows is that 2 airplanes had to return to their departure airport due to transponder problems.
As I mentioned before, there is a long timeline between when problems FIRST begin to occur
& when there is FINALLY a notification or recall issued to all customers.
An Indian offical commented that he had become aware that Boeing 777 & 787 planes with Air India were plagued with transponder problems. That was merely his opinion & not a legal opinion on record. Also he does not speak for the Boeing company.
Furthermore, we can not assume that American policies & practices are universal to other countries.
In fact as far as aviation goes, we already know that the USA runs ALL passports through interpol before takeoff.
And the USA sends up a military jet to investigate every plane who loses communication with air traffic controllers.
Since MH370 went missing, the world sadly learned that Malaysia did NOT perform either of these normal American policies.
All I remember is that the Malaysian government OR Malaysia Airlines vouched that the lithium batteries were properly packed.
I do not believe anyone has yet issued a public comment on the safety features of the confidential cargo.
