Working aircraft in wintery conditions can be tough, but recent
problems with icy runways caused a mess at Chicago's Midway
airport. The controllers claim the airport was a "zoo" on Wednesday
when more than 40 flights were delayed because of ice accumulation
on two runways. The controllers say the ice was there because city
crews failed to clear snow that was leftover from Sunday's winter
storm. Chicago aviation officials disagree with the chilly details
and claim they were unaware of any major traffic delays at the busy
reliever airport.
