Re: To infinity and beyond
There wasn't a patch related to flight four. They discovered before the first flight that there was a timing issue,which they decided not to patch (I think because pushing completely new flight software was sufficiently terrifying) but rather adjust the command sequences so there's something like a 15% chance of hitting a timer during spin-up, which means they need to try again another day. That's what they hit for flight four, and they fid then try again and it was fine. Wnd they'll keep hitting this every few flights, and that's fine.
