Censorship of.. flight details?

A few days ago, a col­leage pointed met at AirSer­vices Australia’s new fancy flight tracker, which allows you to watch planes com­ing and going in the air­space around Syd­ney air­port. There are plenty of things not to like — MS Vir­tual Earth ;) , the nasty click-through EULA that you have to agree to before you even find out what the site provides…

But, that aside, it’s fairly cool. Planes, fly­ing, around Syd­ney! Results from noise-level meters, so you can see just how noisy your new sub­urb is going to be. Even details about the planes — type of plane, alti­tude, flight numbers..

So today there was a tragic acci­dent involv­ing two planes with trainee pilots. SMH have a video online which shows the flight tracker, and shows the two planes involved col­lid­ing (and then one of them drop­ping off the radar — lit­er­ally). Accord­ing to the time­stamps super­im­posed on the video, the crash hap­pens just after 11:23am

The site lets you see his­tor­i­cal data: in the box on the lower-left, un-tick the “Show Cur­rent Flights” but­ton, then use the con­trols to choose the day and time you’d like to look at. So it’s easy enough to go back to 11:20am and run through the next few min­utes and see the crash for yourself.

Except… that it’s not. There are no planes in that area at that time. In fact, there’s no light avi­a­tion at all. Some­one has excised all light avi­a­tion records between 11:00am and 11:59:16am. If you set the timer to start art 10:59, you see a whole bunch of planes:

before

sud­denly dissapear:

after

It’s not a sub­tle removal either, even if you ignore all the planes which freeze and then van­ish from the graph. There’s a nice graph show­ing you the num­ber of move­ments per hour for the day — spot what’s odd about today:

15-1216-1217-1218-12

I fail to under­stand this. I… just fail. I really don’t under­stand why this is con­sid­ered sen­si­tive, and why it’s been removed.

    It’s prob­a­bly down to lia­bil­ity or other legal issues; if this data is avail­able to the pub­lic then you must ask the “log­i­cal ques­tion” about why isn’t there peo­ple watch­ing and try­ing to pre­vent shit like this hap­pen­ing (radar con­trol posi­tions feed­ing D/GAAP TWRs).

    Of course you can’t avoid acci­dents in avi­a­tion and you can’t con­trol every­thing with­out pro­hib­i­tive costs.

      Agree about ask­ing why peo­ple aren’t watch­ing out for this. Not that I’m vol­un­teer­ing to be an ATC — even if I was capa­ble of it, it’s (from what I hear) a very, very stress­ful job (even when you get ade­quate sup­port from man­age­ment, and you’re not work­ing in a coun­try that’s chron­i­cally under­staffed every­where, and…)

      I sus­pect it’s more to do with per­ceived risk of lit­i­ga­tion than actual risk — “We have no idea how this could be bad, but it scares us so let’s just take it down and avoid the risk”.

      You’re right that you can’t avoid acci­dents, but avi­a­tion has a pretty good record. Just think — this was a two-vehicle acci­dent in which two peo­ple died. If that hap­pened on the roads, how much cov­er­age would it get? Maybe a small men­tion, but such things are so com­mon on the roads that it’d drop out of the news cycle within a day.
