On 10th United flt to Houston from London cancelled. Now we hear a Thomson 787 had an air turn-back today. And this Ethiopian flt grounded. What is going on? One thing for sure, the ET fire is not a battery incident. The large Batteries are far away from this fire location. This aircraft has several Remote power distribution panels all over the aircraft and on its ceiling. This looks more like a Galley area fire. But again very strange as no one was on board and no major activity on the aircraft when the fire started.
