Task: Sentiment Analysis
Input (English): Review: I read this book and concluded that I am angry at myself for having read it. Pilots like to read about accidents hoping to study a case and avoid the same mistakes. After wasting your time with worthless and mediocre family stories and the well known government incompetence, you end up with the empty conclusion that a good pilot, in good health, all current and confident ditched in the stormy ocean at night and disappeared. None of the worthless stories or ILS text in this book provides any conclusion or lesson to be learned. A line from Billy Madison comes to mind: "you are now all dumber after hearing this story". In fact the only intelligent thought comes from an opinion of a reader that raises the theory that Ron S. used a GPS approach rather than ILS and that proved fatal. 
 Polarity: Negative
Output (English): True
