Boeing's Dreamliner takes first commercial flight since being grounded in January An official with Ethiopian Airlines says one of the company's Dreamliners is scheduled to fly from Ethiopia to Kenya's capital, the first commercial flight since air safety authorities grounded the passenger jets after incidents with smouldering batteries on two different planes in January. The Boeing 787 passenger jet was scheduled to arrive in Nairobi from Addis Ababa on Saturday afternoon. The U.S. Federal Aviation Administration has approved Boeing's redesigned battery system, which the company says sharply reduces the risk of fire. A Boeing engineer told reporters in Nairobi this week that all potential causes of battery fire have been eliminated with the new system. There are 50 Dreamliners in service around the world. Boeing said Wednesday that deliveries of the 787 should resume in early May.
