Well, I've crashed into invisible rings a few times, but it is not always that easy. If the ring is rendered as a set of concentric rings (despite they all are considered single ring by system map), you can fly through gaps in it without being pulled out of SC. I beive that goes well for invisible rings too.If you can line up correctly, then it's possible to drop out in an invisible ring
