How was the seat accidentally activated and why did it then fail to function properly? The BoI, when it takes place, should focus firmly on those two points. Self medication, mobile phones and other such distractions have nothing to do with the defect in that seat.
You're actually on dangerous ground there Blacksheep and the BOI are well aware of what they need to be looking at. Suffice to say a huge amount of work has gone on in the background since the accident.
