Why do we keep hearing that the problem with the 447 most likely will never be found, when it is becoming obvious what the cause is (cough cough ... Known faulty design of the A330's ADIRU)?? Also, why does the media seem completely ignore to even a reference to the Quantas Flight(s) of 72 (or 71 for that matter), which would seem extremely relevant to the 447 investigation??

I guess my question is this.... Does economics matter more than our butts in the seats of these complex (and sometimes glitch prone) contraptions, or would a temporary grounding just be too economically painful for Airbus to bear?? I understand that they work perfectly 99.8% of the time and most will never report an issue with them, but is it acceptable to have to grit your teeth every time one of these planes go into a little turbulence wondering if the inertial unit will decide to go into "aerobatics" mode??

All of this talk about caring the safety is almost nauseating... If they truly cared about the safety, then why don't they talk to Northrop about truly fixing what they clearly have known for some time is a major issue... Or is the newest strategy to keep letting the body count rise while fighting the issue with a series of ineffective AD's???

Hey I have been out of the loop for awhile (family emergency), but do you have links, or something that explains this ADIRU issue? As a Bus Driver I am intrigued.

Here's a link to the Qantas incident.

Incorrect flight data led Qantas A330 to descend sharply: ATSB

Do not believe that AF had the same ADIRU as Quantas.

ever hear of a concept called risk mgmt? first surfaced with the Pinto - cheaper to pay the claims than put in a $10 shield in front of the gas tank. fastest growing segment in all industries is risk mgmt.

Nice intro as a first post, are you a pilot or a journalist?

I thought the same thing for a minute, but then I remembered there isn't a journalist or reporter with an IQ over 68 left in the world so there is no chance that one of them came up with this.

Neither pilot or journalist...my guess is he/she works for MSNBC or CNN. Just a guess.

I agree look at his grammar. Good sentence structure, complete paragraphs, and no typo's definitely not a pilot.

Uhh, it's because anyone that has been around aviation for more than two years knows that aircraft accidents are never what they seem to be. The causes are many and if there are easy solutions they would have been done a long time ago. Let the accident board do its work.

The approach you are suggesting is akin to a doctor diagnosing your illness by amputating body parts until the pain goes away.
