Many a Western airline or airport manager, begging for better infrastructure, must gaze wistfully at China. There, it is so often said, “the government just gets things done.” And it often seems that when any level of government in China sees a need for roads, power stations, airports and the like, not much time passes before trees are crashing down and excavators are at work. A “Nimbyism” stance does not stand much chance.

BEIJING — South Korea’s program to indigenously develop a stealth fighter is facing severe political obstacles, with the finance ministry seeking to delay development and an influential think tank casting doubt on the project’s viability. In addition, a key program opponent may become defense minister in the next presidential term, which will begin in February.

BEIJING — A second Chinese stealth fighter, apparently from Avic’s Shenyang plant, has appeared in seemingly genuine pictures that cropped up on Chinese web sites Sept. 15. The twin-engine, single-seat fighter, shown at an airfield, appears to approximate the Lockheed Martin F-35 in size, with a somewhat shallower body but a similar span of about 11.4 meters (37.5 ft.), as indicated by comparison with a commercial aircraft tug shown pulling it.
