A report commissioned by Denver International Airport says the facility needs multifunction equipment that can plow, sweep and blow snow -- as part of its plan to stay open during heavy storms.
Two consultants, Critical Path Incorporated, and Landrum and Brown, reviewed the airport's performance during major snowstorms around Christmas last year.
The consultants said the airport's "inability to remove snow from the air carrier ramps began a cascade of events that resulted in an extended airport closure."
The nation's fifth-busiest airport was closed for 45 hours by a storm that started December 20th.
More than 2,000 flights were canceled and about 4,700 travelers were stranded, costing the airlines millions of dollars.
The report said the airport had insufficient people, too few heated garages for snow-removal equipment and insufficient fueling stations.
An earlier draft of the report found the airport's equipment was inadequate for more than four inches of snow from the areas around the boarding gates.
