What happens if and ISAH drive fails?

GC Writer Tech Info Blurb:


 * 1) ISAH drives are utmost dependent on Super Symmetry...Meaning the Isah Field has to be symmetrical, down to the millionth picto qubic.. Entering Quasi Space with a field that is not symmetric...can cause a number of unpredictable incidents..from total destruction,,to YES..being transferred millions of light years..or Sliding past the Quasi Layer and end up in Hyperspace (meaning everything is turned into energy
 * 2) ISAH drives create an ISAH field bubble around the ship if the field is disturbed for any reason real time could leak and mingle with relativistic time and for example age the ship and everything in it for for days, years or...million of years.
 * 3) ISAH drives can fail and the ship is instantly dropped and the sudden deceleration phase kills anyone ...with millions of tons of g forces
