ermm...isn't Hyperspace supposed to be dangerous? I thought you had to let the ship cool down before restarting the process (or am I confusing the whole thing with Star Trek? ) jedi_girl, you're the specialist here, enlighten me please...

Actually you're not mistaken! All ships(feeling weird when saying ship for something going through vacuum, or something like it:?: ) have to cool down before travelling again specially the Millenium Falcon! However in the highly unrealistic SF world, hyperspace is a common practice and is not dangerous. I don't follow Star Trek that much but I guess it must be the same since in this show technology is supposedly very advanced.
Hope I've been of some help!

Talking film wise....
The vacuum thing must be realistic otherwise...

There must be cool down or there should be a marvellous "cooling system" to be able to do short repeated hyperspace jumps.
