There was a third runway up until 2005; it got closed to provide more parking, thus cutting down on airborne holding and, in the process reducing emissions, saving the lives of countless polar bears and sandal-wearing lesbian whales.
-Now can we have our runway back please?
For most of the decade before Runway 23 was taken out of service, it was used on average for a handful of hours per
year, and when it was used it decreased the capacity of the airport.
