Minutes before the crash caused by a missile strike, the AI pilots had also heard the controller give the Malaysian aircraft MH17 what is called "a direct routing". This permits an aircraft to fly straight, instead of tracking the regular route which is generally a zig-zag track that goes from one ground-based navigation aid or way point to another. "Direct routing saves fuel and time and is preferred by pilots. In this case, it proved fatal," said an airline source. Уж не знаю, насколько это имеет отношение к делу, но пусть будет.
