Tulips, I beg to differ only on your remark about a B737 in a similar situation to the Iberia aircraft.
I have flown B737, 747, 757 and 767 in Europe, Middle East and Far East and experienced some really bad weather scenarios, why do you say that a B737 would go,'coventional stall, spin and splat!' whereas the A320 only did a heavy landing? Presumably you are only referring to the action of pulling fully back on the control column by both pilots and having stall protection?
In a B737 and upwards, from my experience, in conditions other than a microburst the Boeings will, with full power and two pilots who know they cannot apply full rearward control without the strong possibility of a stall, climb away.
What makes the Airbus so special?
