I was working when this happened.
There were a LOT of phonecalls and coordination going on between the terminal and the enroute and the tower at this time.
The weather did not help matters when the pilot asked for VFR.
The departures were not affected by the mayday and left as normal, the enroute had been holding arrivals during the emergency and they still accepted departures so they would not be delayed.
A job well done by aircrew and controllers.
