New York - NEW YORK (AP) - Boeing says the results of a key airworthiness test for its long delayed 787 are positive, but it will be weeks before the aircraft maker can deem it a success.
The aircraft manufacturer said Sunday the test involved flexing the jet's wings upward while applying loads to the frame to replicate 150 percent of the most extreme forces the airplane would experience in flight.
The wings were flexed upward by approximately 25 feet (7 1/2 meters) during the test.
Testing takes more than two hours, and thousands of pieces of data were collected to measure wing performance.
Boeing, based in Chicago, says the data will be reviewed over the next several weeks.
