"From an aviation standpoint, closing Crystal Airport
makes no sense. It handles 188,000 operations (takeoffs and
landings) on its four runways annually. That's 94,000 aircraft.
Those aircraft would not just disappear. They'd land someplace else
in the Twin Cities area — most likely in Northwest Airlines'
front yard —- at MSP."

closure of Crystal Airport.
