Oan Orbit
Entering Oan Orbit is tricky at the best of times and sometimes you leave via it without intending to;' depending on whom you annoy whilst on the planet's surface. After it was rebuilt, Oa now has a planetary armor and defense grid dedicated to stopping events like the Blackest Night from ever happening again. Obviously to use Oa's Orbit as a method of getting on the planet, one must have the ability to travel through space and the proper authority/clearance or means to do so.
Once cleared, a person may land on one of the few Oan shuttle bays that there are due to the fact that The Green Lantern Corps have no real need for them.
