I suspect that there will be a number of attempts in various sims to see if Teterboro could have been made with the limited hydraulics available. Mind you that first turn where 1200' was lost likely extinguished interest in any more turns. From 2000' you've got about 6 nautical miles; so, there's a chance they could have got to the runway.
The failure:success ratio will be interesting.
Face it: landing short or not stopping within the runway (how much hydraulics available for the brakes after the glide?) risk significant fatalities.
I don't know what powers the spoilers on the A-320, but if that's hydraulics, there's not much glide path control. Cross controlling for a sideslip with limited hydraulics is test pilot stuff.
Without much in the way of glide path control you want the
longest field you can see.
Looks to me like a conservative choice between a high risk attempt for Teterboro and a super long runway that you already have got made
