LW_50, of course. I'm not concerned about what the actual speed was in terms of this discussion so much as what warnings and annunciations were presented to the pilots. They already knew their speed indications were unreliable, but I suspect things will become clearer once we know what aural warnings were sounding at the time.
Birgenair proved that insistent and contradictory warnings can overwhelm a crew, and procedures were developed in the wake of that incident to better cope with that situation. Were the crew able to recognise their situation and apply those procedures accordingly?
