The Connecticut-based helicopter maker Sikorsky announced on Monday that it will close its Southern Tier plant at the end of the year.

The Vermont Air National Guard is proposing to start taking training flights over the Adirondacks and Watertown with F-35 aircraft.

The big, loud planes would replace the smaller, quieter F-16s the National Guard is using now —but not until at least 2015.

The Guard has issued a draft environmental impact statement – and it has held public hearings  around the area. The planes would take off and land in Burlington, Vermont. A meeting there drew more than 500 people.
