"Could have" they didn't, re rig  the months they were out there.   

As far as "current navigation", you MUST know where you are, even if you have a accurate chart with the current markings.  They were definitely "Off Course" and Lost.  "Following Jet Contrails" you ever attempted that, how long do those last, considering your very slow 5 knot speed how useful are the Jet Contrails.

"It's not rocket science.", having been a Missile Officer, you do not seem to know that "Rockets" have no Brains (guidance navigation controls, G.N.C.s), Missiles have brains, making them "Smart", rockets are pointed in a direction and launched maybe getting where intended.  Missiles are launched and guided.
