For the doubting Thomas who feels this fine lady "should.... have put the gear down with 50 hours of knowledge", imagine you were in an aft seat in the space shuttle and had to suddenly jump in and handle a similar emergency.
Assuming you're a commercial pilot, that's about the same leap you're expecting this lady to make.
If all aboard walked away (and it seems they did) they each owe their lives to her performance!
There's always one, isn't there?
