This is the story of United Airlines flight 1175 from San Francisco to Honolulu, Hawaii. A perfectly smooth flight… followed seconds later by a violent explosion, an almost uncontrollable aircraft…and vibrations…. So many vibrations… Whatever caused this, wasn’t described in any manual.. and as the aircraft started pitching down, the pilots knew that there was only a cold, wavy ocean below them.
