   The problem was  multiple bird strikes, with most probably catastrophic   
   engine failure, I don't think you are going to try a relight in that   
   situation.   
   Do not know who did the ATC call, but that can be handled by the flying   
   pilot.   
   There was no runway to look for, once they decided that TEB was too far,   
   and it seems that the decision to ditch was taken quite quickly, so no   
   really nav selections.   
   Once they decided to ditch because they figured that the engine would   
   not be restarted, then no more relight attempt.   
   If as you say they were going through the relight procedure, they would   
   already had the book in their hands, no need to pick it up, just had to   
   find the right procedure.   
   I do not know about the Airbus, but in a lot of aircraft ditching is   
   considered an emergency, once you decided to ditch that is the emergency   
   procedure you are following.   
      
   Again, maybe the Airbus is different, but for example on my aircraft the   
   ditch switch does more than "sealing" fuselage, it does:   
   -depressurizes the cabin (so you can open the doors)   
   -Shuts down the packs (so no risk of pressurization   
   -closes the outflow valves (so no water can get in.   
      
   Check list also calls for pulling the APU and engines fire handles, you   
   probably don't want to ditch with APU running (or engine you are still   
   trying to relight)
