Sadly for those who would like to believe so we have no evidence that the accident was caused by anything other than pilot actions. Furthermore, this evidence is not likely to be faked or incomplete. What we do have is serious deficiencies in airline procedures and piloting skills which may or may not extend to other carriers besides Air France. There is some anecdotal evidence that training and piloting skills have been neglected outside Air France as well. However, this is an cultural issue not a complexity issue. It is possible to encourage a culture of excellence and professionalism and to reward this. Certain airlines fail to do this and Air France are just the latest example.
