Mr. Kenny Jacobs:

That cold snap in December comes down to this. The one day on which there were issues was 9 December. I happened to be flying myself that morning. As the temperature was minus 4°C, it was a challenging morning for everybody. Our job in this system is to de-ice the taxiways and the runway. Aircraft de-icing is up to the individual airlines. We actually do not de-ice the aircraft.
