Why they say Andreas Lubitz rehearsed Germanwings crash - CNNStory highlights (CNN)French investigators' assertion that Germanwings co-pilot Andreas Lubitz rehearsed a suicide plane crash raises a provocative question: How do they really know he was doing a dry run?"We don't is the short answer," CNN aviation correspondent Richard Quest said.What validates the belief is how Lubitz programmed the high-flying plane several times to descend to an altitude of 100 feet,
http://www.ejiagc.com/sources/news_add.php, Quest said, citing the interim report from French air accident investigators.Those decisions are alarming."You have to remember most pilots would never go to these extremes," Quest said. "They will never ask the aircraft to do something which could be inherently dangerous in such a fashion."Lubitz selected an altitude of 100 feet for three seconds on one occasion and chose the same altitude again for one minute, 47 seconds, another time, Quest said.Germanwings plane crashes in France 26 photosGermanwings plane crashes in France 26 photosA recovery crew works among debris of Germanwings Flight 9525 at the crash site near Seyne-les-Alpes, France, on Friday, April 3.

http://musictheory.jp/wp-includes/js/swfupload/plugins/water.php," Quest said. "He is seeing how it reacts if you do something quite outrageous like set the autopilot to 100 feet instead of say 20,000 or 10,000 (feet) or whatever it is supposed to be."He wants to see, does the Airbus rebel? Does it set off warning noises? Does it take over control? Does the envelope protections suddenly kick in?" Quest said. "And what he discovers of course (is) it doesn't, and then on the return flight, we know what happens."In March, Lubitz deliberately crashed the Airbus A320 into the French Alps,
