Does the CF6 have rollback issues/history (engine icing near CBs?) - Double flame outs would cause electrical system load shedding which would I guess, cause a maintainance event on the ACARS.
Jotape - I'd say Toronto was a pretty major prang, and the Concorde crash was caused by more than just a piece of metal. Further back there was the airshow strimmer at Habsheim, the Strasbourg crash (Air Inter), the 744 off the runway into the drink in the S Pacific etc. (and thats just off the top of my head)!
