Local Wichita television station KAKE reports the layoffs announced this week by Cessna Aircraft total 100 workers. Cessna had not announced totals. The layoffs come in addition to a voluntary retirement program announced earlier this year. Cessna lost $8 million in the first quarter, causing parent company Textron officials to reduce their earnings forecast. A loss is expected in the second quarter too, but profitable quarters are expected to resume late in the year when deliveries of the upgraded Sovereign jet begin.
