I will copy and paste his words on what I think is the most important issue surrounding this accident. All the rest is just so much history rehashed in order to get the thread to the top of the page.
The tragic human cost you refer to is really not in dispute. However with legal proceedings imminent, the key issue will be any finding of negligence that led to the crash and this human cost. Without a finding of negligence, there can be no restitution.
This means all the events leading up to the crash are highly important.
