Where did the data go?
on October 6, 2016

  Data going missing… Recently, our monitoring systems here at Flight Data Services identified that the number of flights processed was slightly down on the expected values, and although this was only a few per cent, it was enough to be concerning as we strive to reach 100% and many customers have data coverage as […]

Defying the Laws of Nature
on September 26, 2016

One of the joys of these blogs is that I can repeatedly show that life is more complicated than you would first think. This blog post follows on naturally from the previous one, in which I clearly stated that you can’t measure something before it happens. No-one contacted me to protest at this bold statement, […]

  Another Spectacular Data Error   For those of you new to flight data, may I offer this week’s blog as a salutary lesson to always expect the unexpected. With only 39 years working with flight data I have never come across an error like this, and it just goes to show that there is […]

Taking a Journey
on July 6, 2016

Philosophically there are two ways to go from one place to another, from an origin to a destination. They are characterized by the saying attributed to Lao Tzu “The journey of a thousand miles begins with one step” and by Eddie Cochran’s hit “Three Steps to Heaven” (where would we be without Google and Wikipedia?).

Beware of Trolls – 2
on June 17, 2016

Beware of Trolls – 2 Here’s an odd not really a blog, more a word of caution. I’ll return to data analysis next week (promise). Still, this week I ask you to watch a video for ten minutes. Back in 2013 I wrote a blog entitled “Beware of Trolls”. This was about patent infringement and […]

A Sample of America
on June 10, 2016

A Sample of America After a few simple blog posts, here is a slightly more tricky one to get your head around. We’ll need to do some background plodding before we get to the meat of the matter. I think it’s worth the effort because, as with all the best stories, there is a surprise […]
