Takata,

In response to you comment: "There was no "reduced crew on the flight deck" either that we are aware of! Pilots were supposed to be at their post as per SOP." My earlier remark was made in...

Agreed, AF447 did not do the impossible.

Machinbird,

The A340 scenario, with a zoom climb resulting in decreased forward velocity followed by a deep stall, with perhaps even a tail down fall to the water, fits the roughly known envelope...

HN39
