New twist in SpaceX rocket blast probe

The mysterious explosion of a SpaceX rocket last month took an odd turn with a "cordial" encounter between staff of Elon Musk's firm and fierce rival United Launch Alliance, The Washington Post reported. No one was hurt in the September 1 blast, which came as the unmanned Falcon 9 rocket was being fueled ahead of a standard, pre-launch test in Cape Canaveral, Florida. Musk is rushing to revolutionize the launch industry by making rocket components reusable.
