[Slasher]

If it is true that a ship that loses it's subspace capability while in transit gets thrown into truespace, then the consequences would be bleak to say the least.  The distances between stars and star systems are vast, and since all known GTVA vessels lack a faster-than-light "warp drive" kind of intersystem transportation mechanism, the ship in question would be stranded and pretty much outta luck.  Unless, of course, it had a way of repairing it's subspace drive and "tapping" back into the intersystem corridor.  Assuming that's even possible.
