[Dune] Long story short our guild navigator is dead. How bad of an idea is it to make a blind jump? Can we do some rough math to improve our chances? What exactly are our chances of living through a blind jump?

New crew member hooked up the Guild Navigator to the waste pipes and a lot of sewage made it into the fish tank he was in. 

Guess he didnt see that coming...

Fortunately, Guild heighliners never really "leave" habitable solar systems. They just jump between them as needed. So unless you've committed the greatest robbery in human history (serously, heighliners are massive and transport gigantic amounts of people and stuff) and took it out to deep space for some reason, you just need to wait for the Guild to send a replacement. And possibly a firing squad for you/your friends. 

Any essential passengers and cargo can be easily offloaded back to the planet and/or other ships waiting nearby so they can get to where they need to go in relatively short order.
