BEIJING — China is firming up figures on the performance of two members of its forthcoming modular rocket family, with suggestions that at least one of the launchers might be a little better than expected. The figures remain patchy, however. The Long March 6, a light rocket designed for prompt launches, will be able to deliver “not less than 1 metric ton” to a Sun-synchronous orbit of 700 km (435 mi.) altitude, says Yu Menglun, a member of the general-design section at CALT, China’s main rocket builder.

BEIJING—The Chinese call it “daxing tumu,” being keen on large-scale construction. It seems that wherever one looks in this country someone is building a mighty new bridge, office tower, airport, freeway or aircraft hangar, more physical capital for the roaring economy.

BEIJING—In early 2008, Avic I, as it was then, announced it was setting up an airline that would buy its regional airliners, a move that had many industry watchers perplexed. To any trenchant doubter of China's future in civil aeronautics, it must have seemed that the product, the 50-60-seat MA60 turboprop, was so uncompetitive that Avic I could only sell it to itself.
