On August 27 I came into Sandbox Goguen on patrol and saw explosions going off in one area. I noticed a lady from JLU in there and got into IM with her. The bombs were rolling in from the north, so I followed them to the very north boundary and discovered that they were dropping down from above. I rose up and found one of those ZX-4 attack choppers with bomb-dropping scripts on it. The bombs would drop on the slope of the hill at the north end of the sandbox, then roll down at great speed quite some distance south.
I notified the JLU lady of the source and tried to do something to stop it, but I had messed up something in my power ring so I couldn't rez anything to help. She looked around and finally rezzed a solid floor beneath the chopper so the bombs fell down, hit the floor, and exploded just below the chopper instead of reaching the sandbox. Some of the bombs were dropping through it anyway, so she rezzed three or four more floors farther down. Another JLU lady showed up, analyzed the bombs, and determined that they were non physical until they touched something. So the two of them built a complex series of boxes and barriers around the chopper and enclosed the whole thing in a giant shield sphere. The whole setup was very impressive. Here's the picture. The winged figure near the top center of the screen is Hawk Woman. Somewhere near the top of the pile is a helicopter, completely encased. My avatar is hovering between the camera and the structure. Fun fun!
