NATIONWIDE AIRLINES SOUTHEAST
Nationwide Airlines Southeast, Inc commenced operations in August 1967 with a small fleet of Beechcraft Queen Airs and a route system based around Atlanta. When founder David Starr departed in late 1968, he was replaced by F.E. "Pete" Howe and the airline was renamed Air South. The following scans are from an undated timetable from 1968.
Some nice shots of Queen Airs N841NS and N842NS.
Here is the complete flight schedule from 1968.
