I thought I'd seen a report of partial deployment. However, I also
remembered reading the report of the Air Transat Landing in the Azores.http://en.wikipedia.org/wiki/Air_Transat_Flight_236
That was an A330. It lost all hydraulics when the engines stopped, which
meant no flaps or spoilers. I didn't recall what type of Airbus that was
and assumed, wrongly, that the same problem would also get the A320.
Reports also said that both engines continued turning after the bird
strikes, but produced insufficient thrust to sustain flight. *They
may, however, have continued generating enough electricity and
hydraulic power for control to be retained.

I think the A320 has a RAT for hydraulics as I doubt you can certify
an airplane that turns into a lawn dart without engine power.
TEB shows a field elevation of 9 feet. There are cliffs between the
airport and the Hudson, but if you are clear of the GW Bridge road
deck you are above the cliffs too. I recall reading a report that the
crew requested clearance into TEB but obviously didn't go there. It
wouldn't have been a straight-in from where they were. At least on the
river there are no obstacles if you end up short of your intended
touch down point.
I've had to make some hard decisions about final glide, but this was
higher stakes than any of those.
