As threatened, the F.A.A. plans to shut 149 small-scale air control towers beginning April 7 as part of the agency’s sequestration implementation plan. These are airports at which air traffic control is managed by workers under contract to the F.A.A.
"We heard from communities
across the country about the importance of their towers and these were
very tough decisions,” said Transportation Secretary Ray LaHood.
“Unfortunately we are faced with a series of difficult choices that we
have to make to reach the required cuts under sequestration."
Flight operations will still be able to continue at these airports, but pilots will need to manage takeoffs and landings by radio among themselves. .
