He pointed to \u201chistorically bad\u201d sea states on the West Coast, which slowed down both booster and fairing recoveries, and cited the bad weather as a reason for slower fairing refurbishment timelines.<\/p>\n<p>He also said the issue with B1086 \u201cgave us a chance to learn and improve the reliability of the entire fleet hence the stand down over the past week.\u201d<\/p>\n<p>\u201cAs much as we love launching rockets, nothing is more important than safety and reliability,\u201d Dontchev wrote. \u201cWe have stood done multiple times simply to double and triple check the everything even if we could have flown that day.
