Bit of a ridiculous question considering we have no idea what happened !
I've never seen so much speculation (see R&N section) on this website - so much so, Danny actually locked the original thread as it was full of armchair enthusiasts wanting to put their two cents worth in.
I for one, would happily get on an Airbus be it for work or pleasure. I think this question would be more relevant if it referred to the 777 incident at LHR, where they could only, (after lengthy investigation) pinpoint a probable cause and not a definite one . . .
