As alluded to in a previous post, JFK, LGA and EWR will hang on to their runway alignments until someone calls a stop to it. All three airports have to change their alignment if one changes.
While it may have been more diplomatically handled, changing runways would make operational/safety sense.....but realigning all three airports has an impact on arrival/departure rates.
For example, JFK will hang onto the Canarsie approach until someone misses or says they won't do it.
The most recent example of an incident/accident I am aware of is hanging on to a 4R approach (with a tailwind). A Gemini MD-11 went off the end (fortunately into an EMAS area) landing in tailwind situation. For those not aware, MD-11's have a very high Vref to begin with. A tailwind adds to the landing energy significantly. If not for EMAS, the damage on the aircraft would have been substantial.
