So, to summarise:
1. No configuration warning check was conducted prior to the start of the take-off roll.
2. The aircraft commenced its take-off ground roll in an incorrect configuration.
3. No configuration warning was generated during the take-off ground roll.
4. After unstick, the aircraft departed from controlled flight, resulting in a fatal accident.
5. No clear cause of the incorrect take-off configuration has been positively determined.
Is that it?
