I truly hope that there is a conclusion drawn from this accident when the final report is published. On first sight it looks very complex. It appears that we are into a what / who failed first endgame.
I have two cars, one is state of the .. and if something quits .. you pay BMW for a new box. The other is 1968 and of UK origin. If something quits you proabably knew about the possibility of failure, and the appropriate action anyway.
Times have changed.
