A computer problem with the FAA automated flight planning system in Atlanta caused major delays at Hartsfield-Jackson Atlanta International Airport, the world's busiest, this morning as well as other airports up and down the East Coast of the US. The computer problem started at about 0500 EST and ended at about 1000 EST. Delays are expected to continue through the rest of today, which were already climbing because of bad weather in the US.

A similar problem happened a year ago August. At that time, the FAA promised that it was working to make sure it never would happen again, just as they promised in 2007.

This article from July in eWeek says that the FAA was transitioning then to a new flight planning system that was supposed to end these types of outages and implied that the transition was almost complete. It is unclear, however, whether this latest problem was in this new system or not.

Why Functional Programming Should Be the Future of Software Development

It’s hard to learn, but your code will produce fewer nasty surprises

You’d expectthe longest and most costly phase in the lifecycle of a software product to be the initial development of the system, when all those great features are first imagined and then created. In fact, the hardest part comes later, during the maintenance phase. That’s when programmers pay the price for the shortcuts they took during development.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
