To clear up a few points for non-737 folk.
Gear warning - probably 'too low gear' due to (faulty) low radalt reading with gear up at 1950'? (would normally be down at that height in my ops in that weather).
As far as I can see, we do NOT know it was a dual channel approach. In any case 'Flare' would not have been armed at the point of radalt fail on such.
A/P should NOT be used on the side with a failed radalt.
I think a radalt of 8ft would cause a retard of the throttles with A/T engaged but NB greb's post above - perhaps the RadAlt had not 'failed'? However, that should be instantly apparent with T/Ls that actually slam shut.
Based on the 'news' so far - I say Monitoring.................!!??? What a sad event. As lederhosen says, 1000' should have been the g/a point.
