From NY times today:

quote
Workers also replaced the suspect part of the chain of electronics

between

controllers and the sensor, known as the point sensor box. The component,
like many parts of the shuttle, is based on 1980's technology and still
uses components like transistors soldered onto circuit boards. (Today,
semiconductor technology places millions of transistors within a single
chip.)

Some of the transistors, which are made by Fairchild Semiconductor, came
from a lot that was suspected of having manufacturing problems, said Steve
Poulos, the manager of NASA's vehicle engineering office.

Really, man with a budget like that you'd expect them to have somebody
redesign those units.
That would only cost a couple of thousand, and less then the travel

expenses

of all the people involved discussing it.

I am not sure I take NASA seriously anymore.
You must be REALLY of your rocker to use 'reject' parts after all that

happened

and with that much money available.
Where did the money REALLY go!

THIS requires an investigation!



"A couple of thousand......." Um, yeah. Like you have a clue about it.

Yep I do, I am electronic designer.

Obviously not a very good one if you can come out with crap like you posted.

And that is kids stuff.
But maybe NASA fired all E designers long ago, and replaced with 'managers' or
idiots like you?
Complete morons to save on a 12 cent part.

*sigh* it's not the cost of the part. Just how many FMEACAs and
certification processes have you been through?

How expensive would it be to put an IC through a full FMEACA? It'd take
years. I use to be a design engineer working on Safety Critical System
(Level 4), it's damned expensive to just replace a part

From a billion $$ project.
Same guys who spend 51 billion on an aniti missile system that does not work?
**** off.

Says he who is talking out of his arse
