Airbus says it will sell 160 commercial passenger jets to China, strengthening suggestions that China may soon become the world's second-biggest aircraft market after the United States. That's what the two big aircraft makers — Airbus and Boeing — predict. The deal pushes Airbus ahead of its U.S. rival in total orders for commercial aircraft this year. Aircraft are sold in dollars, so Airbus is seeing its profits frittered away as the dollar falls against the euro. Last week the head of Airbus went so far as to say the weak dollar was threatening the survival of the world's largest commercial plane maker.
