Boeing delays crew capsule test flights after abort engine problem

Boeing has reshuffled a sequence of test flights planned for the company’s CST-100 Starliner capsule after stuck valves inside a test version of the ship’s service module caused a fuel spill in June, delaying the commercial spacecraft’s first unpiloted orbital demo mission until late this year or early 2019, and moving back the first crew launch to mid-2019, a company official said Wednesday.
