On its final approach to Charlotte, North Carolina, US Air Flight 1016 is suddenly engulfed in rain so intense it obstructs the view from the cockpit. The pilots abort the landing to execute a go-around, but as they do, the aircraft crashes to Earth, hurtling along a road and breaking apart. Among the survivors are the pilots, who insist severe weather is to blame. For the investigators, the extreme rain is only part of the story. While evidence shows it was a microburst that upset the plane, the mystery remains: Why didn't the crew simply fly out?
