...from cutting in on Ticketmaster's turf. Live Nation dumped its ticketing contract with Ticketmaster in January after signing a 10-year contract to license ticketing software from Europe's CTS Eventim to run its own ticketing business. The move took a toll on Ticketmaster, which saw its profits dive 78% in the first quarter, partly due to the lost Live Nation business...
...Wednesday, TIME revisited an October 2008 incident in which a Qantas Airbus 330 - the same model as AF447 - unexpectedly went into a brief yet harrowing 20-second nosedive, causing multiple injuries and requiring an emergency landing. The investigation that followed blamed an ADIRU failure for the 330's uncommanded dive: one of the plane's three ADIRUs, which are designed to help the plane's flight-control computer fly the plane safely, began sending erroneous data spikes to the flight-control computer. Instead of deferring to the information of the two functioning ADIRUs as it normally should, the computer acted...
...involving a different aircraft, on Dec. 27, Airbus combed its computerized flight files and found data fingerprints suggesting similar ADIRU problems had occurred on a total of four flights. One of the earlier instances, in fact, included a September 2006 event on the same plane that entered the uncommanded dive in October (the other three flights had continued safely on). The same VCR-sized ADIRU was to blame in both those cases, although it had supposedly undergone a needed realignment following the 2006 event. All three planes carried the same brand and model of ADIRU...
...known whether Air France 447, an A330, carried the troublesome variety of ADIRU. But if it did, and if the Air France plane plummeted into an uncommanded dive while traveling through a downdraft generated by storms - a common occurrence over the region of the Atlantic Ocean where the plane went down - it could have been doomed as it entered a steep dive and likely broke...
...Australians' March report concluded that the October dive was due to a series of events that, when combined, was "close to the worst possible scenario that could arise from the design limitation in the AOA processing algorithm." Airbus also told investigators that this particular mathematical formula for flying the plane is found only on its A330 and A340 models. "Different algorithms were in use on other Airbus types, which were reported to be more robust to AOA spikes," the report said. "The manufacturer advised that AOA spikes matching the above scenario would not have caused a pitch-down event...
