Comment That loud bang... (Score 1) 106
There was an early report that the lone survivor heard a loud bang.
That could, in theory, mean something major went wrong with the electrical system (yes, a high-amperage system can make some very interesting and loud sounds while failing). If something really bad happened in the aft electronics bay, it could take out the entire main electrical system - both engines feed electrical power through there. Something exploding there could cause the ram air turbine to deploy automatically.
