Software Upgrade Crashes UK Air Traffic Control System
pitpe writes "Earlier today the computer system controlling most of the UK's airspace failed, after tests in preparation for an upgrade failed. The original failure occurred at the West Drayton centre, which is an old (70's) system, as opposed to the new system at Swanage, which has had its own problems. A system wide reboot to fix the system resulted in the entire system being taken down temporarily."
"which is an old (70's) system". As long as it's not 30-year-old hardware then the software should still be fine. Why does everyone think that simply because software was written in the past it is bad?
Considering that up until about 2000, all of the major Air Traffic Control centers in the US were running on vacuum tubes, we were lucky nothing like this ever happened here. Sure, there were glitches at regional centers, that required controllers to do everything by hand, but nothing that required a full reboot of the entire country's ATC system.
Hopefully the UK will get the new system tested and online before it causes more problems!

It seems they have been having problems with their computer systems since 2001 when it was "privatized".
"The air traffic service has been beset by problems since it was partially privatized in 2001. A $484 million center at Swanwick in southern England opened five years late in 2002.
The opening was delayed by problems with computer software, and the glitches continued for months afterward, as controllers misread aircraft altitudes and destinations because of hard-to-decipher computer screens. In at least one case, controllers mistook the Scottish city of Glasgow for Cardiff in Wales.
Now.. that seems like a pretty big mistake for me.. especially for an air traffic controller to do. However, the article later states that:
"Transport Secretary Alistair Darling said Thursday's problem did not lie at Swanwick but at the older West Drayton center, which is due to be closed by 2007."
Thank goodness that old one is closing, however it doesn't sound like its replacement is doing any better!
"If you want to know what is wrong with transport in this country it is that over decades successive governments did not spend enough on the infrastructure and air traffic control is no different," Darling told BBC radio."
Excellent quote! While terrorism is on everyone's mind, we sometimes forget that safety of transportation should also be just as high. I couldn't imagine pilots relying on themselves to fly airplanes amid the thousands of others without the aid of traffic controllers and their computers.
Hmmm.
Perhaps a person experienced in ATC software or hardware could enlighten us on the specific system in use, its OS and other trivial bits.
It would help to reduce the coming surge of Microsoft jokes, which is very likely not relevant here.

Hey, it worked for Samuel L Jackson...
this is a UNIX system, I know this!!!
There is much cruelty in the universe, John.
Yeah, we seem to have the tour map.
National Air Traffic Services http://www.nats.co.uk/services/index.html are the outfit responsible for this.

They have a press release http://www.nats.co.uk/news/news_stories/2004_06_0
Matt Thompson - Actuality - Insert product here.
There are redundant systems in place. Analog radar, humans with brains.
At least there should be. Computers crash, break, have bugs, etc. They're a tool - a more efficient and convenient tool to be sure.
But when they break, there are contingencies so that planes can still take off and land, and wont just fall out of the sky.
This is also why Y2K was such a bunch of stupidity. We really aren't as reliant on computers as people think. We know they crash and are prepared to handle it when they do.
I don't need no instructions to know how to rock!!!!
Much the same thing happened last
week in Dublin
It appears you are trying to land a plane. Would you like to:
[x] Allow Windows to detect new hardware ?
[ ] Allow planes to circle in uncertainty ?
[x] Show this window at all airports
The new centre is at Swanwick in Hampshire, not Swanage in Dorset!!

Swanage is a pleasant little seaside resort. I know it well and stayed there a few nights when on my honeymoon.
Finding Swanwick and Swanage on a map of southern England is left as a exercise. Hint: Mapquest may be a good place to start.

Microsoft has been testing around with flight software since XP called MSFlight.. here's the article to prove it..
Never just test software upgrades on Live systems

My dad is helping the FAA and the US military design and roll out the next gen ATC software here in the US. He comes home and tells stories that make my skin crawl.
The first version of the software was built using standard current interface guidelines and widgets and the testing group that had no experience with older ATC systems were wowed at how simple and yet powerful it was. Pretty much any random person off the street could look at the screen and easily figure out what was going on and how to do various basic tasks. When that version was demoed to the ATC union the union freaked out at how different it was and thus began a cycle of making it more and more backwards.
So, nowadays the next gen ATC software almost exactly replicates the UI of the old non-computerized and semi-computerized systems. On-screen toggle switches and dials, that sort of thing. The FAA and the ATC union have decided that retraining all of their ATCs to use modern computer interfaces would be a Bad Thing. When the computer screen doesn't exactly replicate the interface of the 50+-year-old systems, they freak out and scream bloody murder. On the flip side, kids coming into the field today that have been using computers most of their lives are finding the interface to be counterintuitive to the point of being almost unusable. Middle-aged workers who are both highly proficient ATCs and home computer users report that switching between the two types of interfaces each night when they go home requires conscious effort on their part, since they are so orthogonal.
So who wins? Historical inertia, of course. Why fix the problem today when you can wait for your successors to fix it in 25 years?
