Boeing has undertaken the first of two test flights in an attempt to return its 787 fleet to service. The plane took off near Seattle and Boeing said the two hour flight went according to plan. That will be a relief for a company which has been losing an estimated fifty million dollars a week since regulators grounded the Dreamliner two months ago. The move came after batteries overheated on two separate aircraft one in Boston another in Japan. It is hoping to get the go ahead test for a second test flight within days.
