Two and a half days ago, at around 6:15am local time on December 28, AirAsia flight 8501 (QZ8501) disappeared en route from Indonesia to Singapore. There were 162 passengers and crew on-board, and no survivors have yet been found at the plane's crash site in the Java Sea. Why, in 2014, can we still lose vehicles that are responsible shuttling millions of passengers across the skies every day? Why don't we have real-time tracking of aircraft?
