Boeing stock sinks on report of additional 787 jetliner delays

Boeing Co.'s stock sank Tuesday afternoon after a report that its new 787 jetliner likely will not begin flight testing until June, at least two months later than planned after the company announced a six-month delay last fall. The Wall Street Journal, citing unidentified sources familiar with the 787 program, said Boeing may not power up the plane's electronics until March. It takes two to three months of testing for engineers to clear the plane for flight after the power gets turned on, so that could push flight testing into June. The newspaper said an announcement about a new schedule for test-flying and delivering the 787 could be made as early as Wednesday.
