Cripple,

There seem to be a few red herrings here. The important stuff seems to be:
  • They pulled the CBs (what were they thinking?).
  • Both watched the aircraft roll for 9 seconds to 54° without doing anything.
  • The FO zoom climbed with controlled (not full) backstick.
  • The CP is calling Pull Down repeatedly. The fatal language error?
  • From the stall, the CP is applying full roll with modulated pitch, the FO is applying full back stick with modulated roll.
  • The "stall stall" and "dual input" continue to the impact, with no effect on the crew.

The report is quick to point out that the FO is applying incorrect inputs, but reluctant to report that the CP is doing the same. They key graph is on page 51, with STKPC (decode: stick, pitch, capt).

I'm starting to think that we need to change the stall warning from "STALL STALL" "STALL whoop whoop PUSH DOWN". Or does the industry need a third full-backstick-until-impact event before we make changes?
