Boeing says it has solved software problems with the Delta IV launcher's countdown procedure with the first successful and sixth tanking test at Cape Canaveral. The final test later this month will end with the ignition and brief firing of the cryogenic RS-68 first stage engine. The maiden launch of the US Air Force Evolved Expendable Launch Vehicle on a commercial mission carrying Eutelsat's W5 communications satellite is set for 3 November.
