Design blunders of our times

What idiot puts the entertainment system and the control system of a plane on the same ethernet backbone? Have these fools not heard of air gap security?

They probably have, but they've also considered the weight penalty involved and got scared - especially after looking at the mess cabling made of the A380 launch.

The A380 cabling problem was because some idiot decided to save a few pennies by using aluminium wires rather than copper, but forgot that Al is considerably more brittle, so they got a lot of failures and then had to rewire all the aircraft they'd built once they discovered the error of their ways.

I guess the origin of the problem is similar - idiots making decisions they're not qualified to make and imposing them on the people who understand the technical issues. But then I'm a techie so I would say that :-)

Eh? I thought the German and French design bureaux using different versions of the specialized wiring layout CAD software -- with incompatible file formats and no backward compatability to add to the yucks -- was the root cause of the problem?

Well I'd heard it was the aluminium but there seem to have been problems with the wiring yolks as well, according to ElReg. Maybe it was a number of problems mixed together!

I've found that where budget estimates and/or weight analysis are involved in engineering projects all common sense flies out of the window even when the project is led by former technical managers.

I see the same things in embedded software projects we do when it comes to memory management and processor power.

<a hrefr="http://www.wired.com/politics/security/news/2008/01/dreamliner_security">the entertainment system and the control system</a>

It's a properly formed anchor tag, only the hypertext reference bit has been misspelled "hrefr".
