Google is preparing to overhaul its search engine—

Google is about to start using semantic search techniques to produce search results. The “new Google search engine” will add Wolfram Alpha like results, suggesting that soon it might return just one answer to certain queries, rather than a list of links.

Wolfram Alpha search engine now tracks flight paths, trajectory information. he search engine, which recently began incorporating data from the FAA can now, with a five-minute delay from real-time data, use a flight’s speed, heading and altitude to offer a projection of a plane’s position. A search for ‘flights overhead’ via the Wolfram Alpha web site or app will use your location to pinpoint flights that should be visible to you.
