According to Alan Greenspan, which part of the market could spread to other sectors of the economy?

The reality is that the level of distress here definitely knocked down a couple of notches today. Stocks ended slightly higher, investors paid little attention to a worse-thah-expected inflation report, and comments from former Fed Chairman Alan Greenspan, who said problems in the sub prime mortgage market could spread to other sectors of the economy. So details now, the Dow Industrials as you can see at the Big Board adding 26 points and firmly back above that 12,000 level, the NASDAQ composite are up more than a quarter of a percent, the S&P 500 adding more than a third of a percent.

China has never hidden its desire to become a major force in the aviation in airspace industries. And Sunday’s announcement that plans to challenge Airbus and Boeing’s current duopoly by building big passenger jets isn’t it exactly a shock.
I don’t think there is any surprise that the Chinese are saying that they are good to build their own aircraft in due course. But I think it would at least a couple of decades before they have an aircraft that makes any meaningful dent in the market: and quite possibly several decades.
