Smoke among the Clouds

A new aircraft is launched. Everybody was excited about its maiden flight. People were gearing up for its take off and the crew was ready to fly it over the stratosphere. Suddenly the plane lost contact with the ATC while still in mid-air. The airport went chaotic and the media immediately jumped onto the scene asking various questions. Meanwhile the government sent its naval fleets and Air Force to search for the plane in and around the Indian Ocean. Rough seas hinder the search party and finally it is discovered on the sea bed. When investigations begin various questions pop up and various discoveries are made. But nothing seems to fit in and the puzzle keeps getting complicated. The investigators were confused as to what the real cause of the crash was. But they just knew that superstition was not the final answer. While the black box revealed some interesting facts the chemical tests on various parts had another story to tell. Will the investigators analyze the whole scene and solve the puzzle or will the smoke stand still?
