I have read with interest the many posts re this incident at CNS. Being a KISS man for a career spanning 48 years, all the theory re FLEX, TOGA CONFIG, does not matter a toss once something goes wrong. All a pilot can do is fly the aircraft once he mentally identifies the situation.
Pilots don"t make intentional errors, so perhaps it would be better to focus on what led up to the error in the first place, so hopefully preventing a reoccurrence, rather than the "wotifs"
