I do not want to exclude any posibility.
There is no video camera on the cockpit so we only have the CVR.
The oficial preliminary report states that the crew completed the checklist.
They say nothing about rushing items or missing items. Anyone that has flown in Barajas knows the long taxi to the runway so they should have not rushed any items anyway.
The report concludes the crew was performing the appropiate checklist.
No comments there, nothing was rushed, ommited or neglected, but still some people wonders if the pilots may have been doing some wrong
Seems that for some people here it is easier to assume that the crew was just reading a checklist but not doing their job rather to assume that a not uncommon flap/slat extension failure happened.
You must forgive me but without discarding any possibilities I prefer to think that if one pilot was challenged with the "Flaps and Slats" question and he positively answered "Flaps and Slats OK" he meant that.
If you want me to change my mind about that, demonstrate it otherwise.
