Boeing 787 Dreamliner takes maiden commercial flight Boeing's much-lauded Dreamliner flew into the skies and the history books on Saturday. An Ethiopian airlines flight to Kenya was Boeing's maiden commercial flight since air safety authorities grounded the new 787 passenger jets in January after incidents with smouldering batteries on two different planes. At a press conference in Japan, Boeing was at pains to point out that all the safety issues had been ironed out and that the planes were now fully safe to fly. Their chief engineer and 787 project leader Michael Sinnett said: Because we know that the enclosure can protect the airplane from the worst case battery failure, in some ways it almost doesn't matter what the root cause was. The Japanese air authorities have already approved Dreamliner flights for operational use, provided they have all been fitted with the new reinforced batteries. More about: Airlines, Boeing, Ethiopia
