Where's that plane overhead going? Wolfram Alpha knows

That sounds cool. Wolfram Alpha, if I remember correctly is the brain behind SIRI. It would surely be good to know more about it. Also if it can be used in more places it will be great. Time to get to know more about it!

Wol­fram Alpha, the search engine that's more than just a search engine, has added a neat new trick to its reper­toire: it can now answer the ques­tion, "where is that plane over­head going?" More than that, it can tell you where the flight's com­ing from, what air­line is oper­at­ing it, the alti­tude the plane is fly­ing at, and even its angle from the hori­zon rel­a­tive to you. All that info is com­ing into Wol­fram Alpha from the US Fed­er­al Avi­a­tion Admin­is­tra­tion, though it arrives with a five-minute delay that means Wol­fram's real time data is actu­al­ly a pro­jec­tion of each plane's posi­tion — cal­cu­lat­ed on the basis of its last known head­ing, speed, and alti­tude — rather than a per­fect­ly accu­rate mea­sure­ment. Anoth­er lim­i­ta­tion that aris­es from the source of the data is that the "flights over­head" search string only …
