Delta IV software fault delays booster mission

The software glitch that caused the aborted first wet countdown demonstration test of the first Boeing Delta IV at T-5 minutes on 30 August, is going to delay maiden flight of the booster, carrying Eutelsat W5, from 11 October to later that month or early November. Two more countdown rehearsals are due at Cape Canaveral's refurbished Pad 37, the final test culminating in the firing of the new Boeing RS-68 cryogenic first stage engine for five seconds.
