The MH370 disaster has been one of the worst disasters in Aviation History. A whole airplane just disappeared out of the sky. This comes in an age, where it is extremely hard for even a person to disappear, let alone an object with as much security as an entire airliner. This happened about 2 years ago, and only recently has debris from the flight started to wash up on the shores of Africa. Another problem is that even today, nobody knows the cause of the accident, and at the rate that this investigation is going, no one will ever know.
On a routine flight from Kuala Lumpur Malaysia to Beijing in China, a Boeing 777, operated by Malaysian Airlines as flight MH370 simply dropped out of the sky, never to be heard from again. About a year or so passed before debris started washing up on the French island of Reunion. Recently though there have been 2 discoveries, the first on the island of Mauritius, and the other off the coast of South Africa. Both discoveries have been confirmed as wreckage from Flight MH370, and proof that the plane went down in the area that they thought it did. Sadly it is unlikely that we will ever know the cause of the crash, since it will be really hard to find the black boxes from this flight.
To Conclude the MH370 crash is one of the worst disasters in modern aviation history, and it is one of the few that is unlikely to be solved anytime soon.
