Cessna announces additional layoffs

WICHITA, Kan. — Cessna Aircraft Co., the nation’s largest builder of corporate jets, said Friday it is laying off an additional 1,300 workers as the recession has depressed demand for its planes. It said the cutbacks will affect all its facilities.

Cessna has laid off about half of its employees since the first round of cuts was announced in November. The company employed nearly 16,000 people last year — including about 12,000 in Wichita — before the economic downturn slashed global demand for corporate aircraft.

Computer glitch briefly halts trading of stocks

NEW YORK — A computer glitch briefly halted trading on the floor of the New York Stock Exchange for more than 200 stocks.

The disruption Friday hit 242 stocks, including American Express Co., General Electric Co., Merck & Co. and Exxon Mobil Corp., but they continued to be traded electronically without disruption. About 3,100 stocks are traded at the NYSE.

The trading halt affected how the Dow Jones industrial average was calculated. Of the index’s 30 stocks, 27 trade at the Big Board. Eight of the stocks were halted on the floor.
