Guess who's back, back again? Dreamliner's back, tell a friend!

An Ethiopian Airlines flight has taken off from Addis Ababa, and is travelling to Nairobi in Kenya at time of writing. So where's the fanfare in that? It is the first commercial flight by the Boeing 787 Dreamliner since all 787s were grounded in January. The 50 787s in service around the world were grounded due to battery malfunctions that saw one 787 catch fire in the US. Over the past week, teams of Boeing engineers have been fitting new batteries to the aircraft. This was after aviation authorities approved the revamped battery design. In other plane-related news, New York police say what appears to be part of the landing gear of one of jets flown into the World Trade Center on 11 September 2001 has been found. The 5ft (1.52m) piece of metal, which bears a Boeing label and serial number, was wedged between two New York City buildings, police said. It was found on Wednesday by surveyors inspecting a lower Manhattan building. But enough about that historic find because starting on Monday, 5,000 Britons will be challenging themselves to live on just £1 a day for five days, as part of a campaign by the Global Poverty Project. But is it possible not just to survive, but also to eat a balanced and healthy diet on that sort of budget? Let's wait and see. It could be something worth trying. And speaking of trying, a US citizen is soon to go on trial on charges including attempting to overthrow North Korea's government, according to the Korean Central News Agency (KCNA). KCNA says that Pae Jun-Ho, who is known in the US as Kenneth Bae, has admitted the charges, without specifying when the trial will start. Pae/Bae was held last year after entering North Korea as a tourist.
