The test flight of one of Boeing 787 Dreamliner test airplanes had to be cut short as the pilot chose to land the plane early due to some maintenance issue. Boeing said the diversion was only precautionary and the hour-long flight is still considered a success.
The plane is one of two 787 flight test planes with GE engines. The other four have Rolls-Royce engines. Boeing hopes to deliver the first 787 early next year, more than two years late.
